CodeGen: Fix pointer info in SplitVecOp_EXTRACT_VECTOR_ELT/SplitVecRes_INSERT_VECTOR_ELT
Two issues found when doing codegen for splitting vector with non-zero alloca addr space:
DAGTypeLegalizer::SplitVecRes_INSERT_VECTOR_ELT/SplitVecOp_EXTRACT_VECTOR_ELT uses dummy pointer info for creating
SDStore. Since one pointer operand contains multiply and add, InferPointerInfo is unable to
infer the correct pointer info, which ends up with a dummy pointer info for the target to lower
store and results in isel failure. The fix is to introduce MachinePointerInfo::getUnknownStack to
represent MachinePointerInfo which is known in alloca address space but without other information.
TargetLowering::getVectorElementPointer uses value type of pointer in addr space 0 for
multiplication of index and then add it to the pointer. However the pointer may be in an addr
space which has different size than addr space 0. The fix is to use the pointer value type for
index multiplication.

[MachineOutliner] NFC: Throw out self-intersections on candidates early
Currently, the outliner considers candidates that intersect with themselves in
the candidate pruning step. That is, candidates of the form "AA" in ranges like
"AAAAAA". In that range, it looks like there are 5 instances of "AA" that could
possibly be outlined, and that's considered in the benefit calculation.
However, only at most 3 instances of "AA" could ever be outlined in "AAAAAA".
Thus, it's possible to pass through "AA" to the candidate selection step even
though it's *never* the case that "AA" could be outlined. This makes it so that
when we find candidates, we consider only non-overlapping occurrences of that
candidate.

The test case was found by a java fuzzer and reduced. It's a real cornercase. You have to have a static loop which we've already proven only executes once, but haven't broken the backedge on, and an inner phi whose result can be constant folded by SCEV using exit count reasoning but not proven by isKnownPredicate.

IR printing improvement for function passes - introducing -print-module-scope

When debugging function passes it happens to be rather useful to dump
the whole module before the transformation and then use this dump
to analyze this single transformation by running it separately

Introducing
-print-module-scope
debugging option that forces all the function-level IR dumps
to become whole-module dumps.
This option builds on top of normal dumping controls like
-print-before/after
-filter-print-funcs
The plan is to eventually extend this option to cover other local passes
(at least loop passes) but that should go as a separate change.

[X86] Improvement in CodeGen instruction selection for LEAs.
Summary:
1/ Operand folding during complex pattern matching for LEAs has been extended, such that it promotes Scale to
accommodate similar operand appearing in the DAG e.g.
T1 = A + B
T2 = T1 + 10
T3 = T2 + A
For above DAG rooted at T3, X86AddressMode will now look like
Base = B , Index = A , Scale = 2 , Disp = 10
2/ During OptimizeLEAPass down the pipeline factorization is now performed over LEAs so that if there is an opportunity
then complex LEAs (having 3 operands) could be factored out e.g.
leal 1(%rax,%rcx,1), %rdx
leal 1(%rax,%rcx,2), %rcx
will be factored as following
leal 1(%rax,%rcx,1), %rdx
leal (%rdx,%rcx) , %edx
3/ Aggressive operand folding for AM based selection for LEAs is sensitive to loops, thus avoiding creation of any complex LEAs within a loop.
4/ Simplify LEA converts (lea (BASE,1,INDEX,0) --> add (BASE, INDEX) which offers better through put.
PR32755 will be taken care of by this pathc.

Add flag to ArchiveWriter to test GNU64 format more efficiently
Even with the sparse file optimizations the SYM64 test can still be painfully
slow. This unnecessarily slows down devs. It's critical that we test that the
switch to the SYM64 format occurs at 4GB but there isn't any better of a way to
fake the size of the file than sparse files. This change introduces a flag that
allows the cutoff to be arbitrarily set to whatever power of two is desired.
The flag is hidden as it really isn't meant to be used outside this one test.
This is unfortunate but appears necessary, at least until the average hard
drive is much faster.
The changes to the test require some explanation. Prior to this change we knew
that the SYM64 format was being used because the file was simply too large to
have validly handled this case if the SYM64 format were not used. To ensure
that the SYM64 format is still being used I am grepping the file for "SYM64".
Without changing the filename however this would be pointless because "SYM64"
would occur in the file either way. So the filename of the test is also changed
in order to avoid this issue.

90% of them are already hidden, but when people add new options they
forget to hide them, so if you were to make a brand new tool today, link

This was storing the hash alongside the key so that the hash
doesn't need to be re-computed every time, but in doing so it
was allocating a structure to keep the key size small in the

indirection on every probe, and this cost of this pointer
indirection ends up being higher than the cost of having a

[llvm] Add stripped installation targets
CMake's generated installation scripts support `CMAKE_INSTALL_DO_STRIP`
to enable stripping the installed binaries. LLVM's build system doesn't
expose this option to the `install-` targets, but it's useful in
conjunction with `install-distribution`.
Add a new function to create the install targets, which creates both the
regular install target and a second install target that strips during
installation. Change the creation of all installation targets to use
this new function. Stripping doesn't make a whole lot of sense for some
installation targets (e.g. the LLVM headers), but consistency doesn't
hurt.
I'll make other repositories (e.g. clang, compiler-rt) use this in a
follow-up, and then add an `install-distribution-stripped` target to
actually accomplish the end goal of creating a stripped distribution. I
don't want to do that step yet because the creation of that target would
depend on the presence of the `install-*-stripped` target for each
distribution component, and the distribution components from other
repositories will be missing that target right now.

[llvm-objcopy] Add support for --only-keep/-j and --keep
This change adds support for the --only-keep option and the -j alias as well.
A common use case for these being used together is to dump a specific section's
data. Additionally the --keep option is added (GNU objcopy doesn't have this)
to avoid removing a bunch of things. This allows people to err on the side of
stripping aggressively and then to keep the specific bits that they need for
their application.

[cmake] Include project name in Sphinx doctree dir to fix race conditions
Modify add_sphinx_target() to include the project name alongside builder
in Sphinx doctree directory. This aims to avoid crashes due to race
conditions between multiple Sphinx instances running in parallel that
attempt to create or read that directory simultaneously.
This problem has originally been addressed in r283188. However, that
commit presumed that there will be only one target per builder being
run. However, r314863 introduced a second manpage target, reintroducing
the race condition.

In rare cases we can receive request to inject into completelly empty basic block. In the normal case
all basic blocks contain at least terminator instruction, but it is possible that the only instruction is
catchpad instruction which is not part of the instruction iterator. This case seems rare enough to not care
about it.
