Regalloc creates COPY instructions which do not formally use VALU.
That results in v_mov instructions displaced after exec mask modification.
One pass which do it is SIOptimizeExecMasking, but potentially it can be
done by other passes too.
This patch adds a pass immediately after regalloc to add implicit exec
use operand to all VGPR copy instructions.

pc_array_size and kPcArrayMaxSize appear to be measured in elements, not
bytes, so we shouldn't multiply idx by sizeof(uptr) in this bounds
check. 32-bit Chrome was tripping this assertion because it has 64
million coverage points. I don't think it's worth adding a test that has
that many coverage points.

Summary:
When conditional branches with complex conditions are split into
multiple branches in SelectionDAGBuilder::FindMergedConditions, also
handle inverted conditions. These may sometimes appear without having
been optimized by InstCombine when CodeGenPrepare decides to sink and
duplicate cmp instructions, causing them to have only one use. This
problem can be increased by e.g. GVNHoist hiding more cmps from
InstCombine by combining equivalent cmps from different blocks.
For example codegen X & !(Y | Z) as:
jmp_if_X TmpBB
jmp FBB
TmpBB:
jmp_if_notY Tmp2BB
jmp FBB
Tmp2BB:
jmp_if_notZ TBB
jmp FBB

On android API level 9 the header does not get included transitively.
Include it directly.
As far as I can see, all non-windows platforms should have this header.
If that turns out to be incorrect, we can add some ifdefs around that.

a lazy-asserting PoisoningVH.
AssertVH is fundamentally incompatible with cache-invalidation of
analysis results. The invaliadtion happens after the AssertingVH has
already fired. Instead, use a PoisoningVH that will assert if the
dangling handle is ever used rather than merely be assigned or
destroyed.
This patch also removes all of the (numerous) doomed attempts to work
around this fundamental incompatibility. It is a pretty significant
simplification IMO.
The most interesting change is in the Inliner where we still do some
clearing because we don't want to rely on the coarse grained
invalidation strategy of the containing pass manager. However, I prefer
the approach that contains this logic to the cleanup phase of the
Inliner, and I think we could enhance the CGSCC analysis management
layer to make this even better in the future if desired.
The rest is straight cleanup.
I've also added a test for one of the harder cases to work around: when
a *module analysis* contains many AssertingVHes pointing at functions.

AssertingVH that delays any reported error until the handle is *used*.
This allows data structures to contain handles which become dangling
provided the data structure is cleaned up afterward rather than used for
anything interesting.
The implementation is moderately horrible in part because it works to
leave AssertingVH in place, undisturbed. If at some point there is
consensus that this is simply how AssertingVH should be used, it can be
substantially simplified.
This remains a boring pointer in a non-asserts build as you would
expect. The only place we pay cost is in asserts builds.
I plan to use this as a basis for replacing the asserting VHs that
currently dangle in the new PM until invalidation occurs in both LVI and
SCEV.

Summary:
Use the O_CLOEXEC flag only when it is available. Some old systems (e.g.
SLES10) do not support this flag. POSIX explicitly guarantees that this
flag can be checked for using #if, so there is no need for a CMake
check.
In case O_CLOEXEC is not supported, fall back to fcntl(FD_CLOEXEC)
instead.

The sh_info field of the SHT_SYMTAB section holds the index for the
first non-local symbol. When there are global symbols that are output
with STB_LOCAL binding due to having hidden visibility or matching
the local version from a version script, the calculated value of
NumLocals + 1 does not account for them. This change accounts for
global symbols being output with local binding.

Summary:
This fixes a regression caused by D28397, which switched lld from using
add_llvm_library to llvm_add_library. The latter does not automatically set up
install rules for libraries, as it's expected the project will set them up
manually based on its own needs.
This adds the install rules to add_lld_library for lld. They were inspired by
the similar add_clang_library macro in clang.
