[llvm-go] parameterize $GOPATH construction
Summary:
To build llgo, you must currently ensure that llgo
is in the tools/llgo directory, due to a hard-coded
path in llvm-go.
To support the use of LLVM_EXTERNAL_LLGO_SOURCE_DIR,
we introduce a flag to llvm-go that enables the
caller to specify the paths to symlink in the
temporary $GOPATH.

Consider this case:

vreg2 = A2_zxth vreg1 (2)
Redundant instruction elimination could delete the instruction (1)
because the user (2) only cares about the low 16 bits. Then it could
delete (2) because the input is already zero-extended. The problem
is that the properties allowing each individual instruction to be
deleted depend on the existence of the other instruction, so either
one can be deleted, but not both.
The existing check for this situation in RIE was insufficient. The
fix is to update all dependent cells when an instruction is removed

[ARM] Implement -mimplicit-it assembler option
This option, compatible with gas's -mimplicit-it, controls the
generation/checking of implicit IT blocks in ARM/Thumb assembly.
This option allows two behaviours that were not possible before:
- When in ARM mode, emit a warning when assembling a conditional
instruction that is not in an IT block. This is enabled with
-mimplicit-it=never and -mimplicit-it=thumb.
- When in Thumb mode, automatically generate IT instructions when an
instruction with a condition code appears outside of an IT block. This
is enabled with -mimplicit-it=thumb and -mimplicit-it=always.
The default option is -mimplicit-it=arm, which matches the existing
behaviour (allow conditional ARM instructions outside IT blocks without
warning, and error if a conditional Thumb instruction is outside an IT
block).
The general strategy for generating IT blocks in Thumb mode is to keep a
small list of instructions which should be in the IT block, and only
emit them when we encounter something in the input which means we cannot
continue the block. This could be caused by:
- A non-predicable instruction
- An instruction with a condition not compatible with the IT block
- The IT block already contains 4 instructions
- A branch-like instruction (including ALU instructions with the PC as
the destination), which cannot appear in the middle of an IT block
- A label (branching into an IT block is not legal)
- A change of section, architecture, ISA, etc
- The end of the assembly file.
Some of these, such as change of section and end of file, are parsed
outside of the ARM asm parser, so I've added a new virtual function to
AsmParser to ensure any previously-parsed instructions have been
emitted. The ARM implementation of this flushes the currently pending IT
block.
We now have to try instruction matching up to 3 times, because we cannot
know if the current IT block is valid before matching, and instruction
matching changes depending on the IT block state (due to the 16-bit ALU
instructions, which set the flags iff not in an IT block). In the common
case of not having an open implicit IT block and the instruction being
matched not needing one, we still only have to run the matcher once.
I've removed the ITState.FirstCond variable, because it does not store
any information that isn't already represented by CurPosition. I've also
updated the comment on CurPosition to accurately describe it's meaning
(which this patch doesn't change).

[CMake] Support feeding DYLD_LIBRARY_PATH into archiver calls
OS X 10.11 has a feature named System Integrity Protection. The goal of the feature is to make system binaries immutable (even as root). One part of this is that protected binaries do not receive DYLD_* environment variables because the kernel scrubs them before process launch.
This causes problems for LTO bootstrap builds on Darwin that try to use the just-built libLTO with the host ar, ranlib, or libtool.
This patch addresses two problems.
(1) The tools themselves aren't protected binaries but the shim tools installed at / are, so we need to call xcrun -find to find libtool instead of using the one CMake finds.
(2) Some build tools (ninja and make) use /bin/sh to invoke their subprocesses. Since /bin/sh is a system binary, the kernel scrubs the DYLD envars from their environment. To work around this we need to set the environment variables as part of the archiver commands, so the envars are set by the shell process instead of on the shell process.

Next step along the way to getting good error messages for bad archives.
I consulted with Lang Hames on this work, and the goal was to add a bit
of "where" in the archive the error occurred along with what the error was.
So this step changes ArchiveMemberHeader into a class with a pointer
to the archive header and the parent archive. Which allows the methods
in the ArchiveMemberHeader to determine which member the header is
for to include that information in the error message.
For this first step the "where" is just the offset to the member in the
archive. The next step will be a new method on ArchiveMemberHeader
to get the full name, if possible, to be use in the error message. Which
will now be possible as ArchiveMemberHeader contains a pointer to
the Archive with its string table and its size, etc. so the full name can
be determined from the header if it is valid.
Also this change adds the missing checks the archive header is actually
contained in the buffer and is not truncated, as well as if the terminating
characters are correct in the header.
And changes one error message in Archive::Child::getNext() where the
name or offset to member is now added.

Pre-instrumentation inline (pre-inliner) greatly improves the IR
instrumentation code performance, among other benefits. One issue of the

is due to the fact that the same COMDAT function may have different early
inline decisions across different modules -- that means different copies
of COMDAT functions will have different CFG checksum.
In this patch, we propose a partially renaming the COMDAT group and its

StringSwitch cannot be copied (take 2).
This prevents StringSwitch from being used with 'auto', which is
important because the inferred type is StringSwitch rather than the
result type. This is a problem because StringSwitch stores addresses
of temporary values rather than copying or moving the value into its
own storage.
This is a compromise that still allows wrapping StringSwitch in other
temporary structures, which (unlike StringSwitch) may be non-trivial
to set up and therefore want to at least be movable. (For an example,
see QueryParser.cpp in clang-tools-extra.)

Revert "StringSwitch cannot be copied or moved."
This reverts commit r276652. The clang-query tool is currently
relying on this behavior. I'll try again later.

MC] Provide an MCTargetOptions to implementors of MCAsmBackendCtorTy, NFC
Some targets, notably AArch64 for ILP32, have different relocation encodings
based upon the ABI. This is an enabling change, so a future patch can use the
ABIName from MCTargetOptions to chose which relocations to use. Tested using
check-llvm.
The corresponding change to clang is in: http://reviews.llvm.org/D16538

StringSwitch cannot be copied or moved.
...but most importantly, it cannot be used well with 'auto', because
the inferred type is StringSwitch rather than the result type. This
is a problem because StringSwitch stores addresses of temporary
values rather than copying or moving the value into its own storage.
Changing this uncovered the bug in PassBuilder, also in this patch.
Clang doesn't seem to have any occurrences of the issue.
