[ARM] Support constant pools in data when generating execute-only code.
The ARM backend asserts against constant pool lowering when it generates
execute-only code in order to prevent the generation of constant pools in
the text section. It appears that target independent optimizations might
generate DAG nodes that represent constant pools. By lowering such nodes
as global addresses we don't violate the semantics of execute-only code
and also it is guaranteed that execute-only behaves correct with the
position-independent addressing modes that support execute-only code.

Align definition of DW_OP_plus with DWARF spec [3/3]
Summary:
This patch is part of 3 patches that together form a single patch, but must be introduced in stages in order not to break things.
The way that LLVM interprets DW_OP_plus in DIExpression nodes is basically that of the DW_OP_plus_uconst operator since LLVM expects an unsigned constant operand. This unnecessarily restricts the DW_OP_plus operator, preventing it from being used to describe the evaluation of runtime values on the expression stack. These patches try to align the semantics of DW_OP_plus and DW_OP_minus with that of the DWARF definition, which pops two elements off the expression stack, performs the operation and pushes the result back on the stack.
This is done in three stages:
• The first patch (LLVM) adds support for DW_OP_plus_uconst.
• The second patch (Clang) contains changes all its uses from DW_OP_plus to DW_OP_plus_uconst.
• The third patch (LLVM) changes the semantics of DW_OP_plus and DW_OP_minus to be in line with its DWARF meaning. This patch includes the bitcode upgrade from legacy DIExpressions.

Align definition of DW_OP_plus with DWARF spec [1/3]
Summary:
This patch is part of 3 patches that together form a single patch, but must be introduced in stages in order not to break things.
The way that LLVM interprets DW_OP_plus in DIExpression nodes is basically that of the DW_OP_plus_uconst operator since LLVM expects an unsigned constant operand. This unnecessarily restricts the DW_OP_plus operator, preventing it from being used to describe the evaluation of runtime values on the expression stack. These patches try to align the semantics of DW_OP_plus and DW_OP_minus with that of the DWARF definition, which pops two elements off the expression stack, performs the operation and pushes the result back on the stack.
This is done in three stages:
• The first patch (LLVM) adds support for DW_OP_plus_uconst.
• The second patch (Clang) contains changes all its uses from DW_OP_plus to DW_OP_plus_uconst.
• The third patch (LLVM) changes the semantics of DW_OP_plus and DW_OP_minus to be in line with its DWARF meaning. This patch includes the bitcode upgrade from legacy DIExpressions.

[IR] Stop deleting other signatures of User::operator new when we override one signature in a class derived from User
User has 3 signatures for operator new today. They take a single size, a size and a number of users, and a size, number of users, and descriptor size.
Historically there used to only be one signature that took size and a number of uses. Long ago derived classes implemented their own versions that took just a size and would call the size and use count version. Then they left an unimplemented signature for the size and use count signature from User. As we moved to C++11 this unimplemented signature because = delete.
Since then operator new has picked up two new signatures for operator new. But when the 3 argument version was added it was never added to the delete list in all of the derived classes where the 2 argument version is deleted. This makes things inconsistent.
I believe once one version of operator new is created in a derived class name hiding will take care of making all of the base class signatures unavailable. So I don't think the deleted lines are needed at all.
This patch removes all of the deletes in cases where there is an override or there is already a delete of another signature (that should trigger name hiding too).

Support: Don't set RLIMIT_AS on child processes when applying a memory limit
It doesn't seem relevant to set an address space limit - this isn't
important in any sense that I'm aware & it gets in the way of things
that use a lot of address space, like llvm-symbolizer.
This came up when I realized that bugpoint regression tests were much
slower with -gsplit-dwarf than plain -g. Turned out that bugpoint
subprocesses (opt, etc) were crashing and doing symbolization - but
bugpoint runs those subprocesses with a 400MB memory limit. So with
plain -g, mmaping the opt binary would exceed the memory limit, fail,
and thus be really fast - no symbolization occurred. Whereas with
-gsplit-dwarf, comically, having less to map in, it would succeed and
then spend lots of time symbolizing.
I've fixed at least the critical part of bugpoint's perf problem there
by adding an option to allow bugpoint to disable symbolization. Thus
improving the perfromance for -gsplit-dwarf and making the -g-esque
speed available without this quirk/accidental benefit.

[RS4GC] Drop invalid metadata after pointers are relocated
Summary:
After RS4GC, we should drop metadata that is no longer valid. These metadata
is used by optimizations scheduled after RS4GC, and can cause a miscompile.
One such metadata is invariant.load which is used by LICM sinking transform.
After rewriting statepoints, the address of a load maybe relocated. With
invariant.load metadata on a load instruction, LICM sinking assumes the
loaded value (from a dererenceable address) to be invariant, and
rematerializes the load operand and the load at the exit block.
This transforms the IR to have an unrelocated use of the
address after a statepoint, which is incorrect.
Other metadata we conservatively remove are related to
dereferenceability and noalias metadata.
This patch drops such metadata on store and load instructions after
rewriting statepoints.

[ADT] Reduce duplication between {Contextual,}FoldingSet; NFC
This is a precursor to another change (coming soon) that aims to make
FoldingSet's API more type-safe. Without this, the type-safety change
would just duplicate 4 more public methods between the already very
similar classes.
This renames FoldingSetImpl to FoldingSetBase so it's consistent with
the FooBase -> FooImpl<T> -> Foo<T> convention we seem to have with
other containers.

AArch64: don't try to emit an add (shifted reg) for SP.
The "Add/sub (shifted reg)" instructions use the 31 encoding for xzr and wzr
rather than the SP, so we need to use different variants.
Situations where this actually comes up are rare enough (see test-case) that I
think falling back to DAG is fine.

[llvm-ar] Make llvm-lib behave more like the MSVC archiver
Summary:
Use the filepath used to open the archive member as the archive member
name instead of the file basename. This path might be absolute or
relative. This is important because the archive member name will show
up in the PDB, and we want our PDBs to look as much like MSVC's as
possible.
This also helps avoid an issue in our PDB module descriptor writing
code, which assumes that all module names are unique. Relative paths
still aren't guaranteed to be unique, but they're much better than
basenames, which definitely aren't unique.

Power9 has instructions that will reverse the bytes within an element for all

shuffle nodes as that will cover both the builtins and vector shuffles that
occur in the SDAG through other means.
