The FIXME comments were about preventing load folding to avoid a partial xmm update. But these instructions use GPR as input when the load isn't folded. This won't help prevent a partial xmm update.

Fuchsia uses ELF as a file format and LLD as the linker so we can
use the same implementation as other ELF based platforms.

This gives us something to insert into the shadow gap for systems that
don't have memory protection turned on there (i.e. on Myriad).

r332057 introduced distance() for ranges. Based on post-commit feedback,
this renames distance() to size(). The new size() is also only enabled
when the operation is O(1).

We need to clean up the DAG floating-point undef logic.
This process is similar to how we handled integer undef
logic in D43141.
And as we did there, I'm trying to reduce the patch by
changing tests that would probably become meaningless
once we correct FP undef folding.

Some *_l functions were not available in some versions of Bionic. This CL
checks that the NDK version supports the functions, and if not, falls back
on the corresponding functions that don't take a locale.

Summary:
Same as r332530, move WasmSymbol::dump to an implementation file to avoid linker
issues when the dump function is seen in the header, doesn't get eliminated, and
then linking fails because of the missing dependency.

VSOs now track dependencies for materializing symbols. Each symbol must have its
dependencies registered with the VSO prior to finalization. Usually this will
involve registering the dependencies returned in
AsynchronousSymbolQuery::ResolutionResults for queries made while linking the
symbols being materialized.
Queries against symbols are notified that a symbol is ready once it and all of
its transitive dependencies are finalized, allowing compilation work to be
broken up and moved between threads without queries returning until their
symbols fully safe to access / execute.
Related utilities (VSO, MaterializationUnit, MaterializationResponsibility) are
updated to support dependence tracking and more explicitly track responsibility
for symbols from the point of definition until they are finalized.

Summary:
r332305 added a use of llvm::wasm::toString in llvm::object::WasmSymbol::print,
which is in a header file. It also moves toString to BinaryFormat. This has the
unintended side-effect that any inclusion of Object/Wasm.h now relies on
toString, and needs to required_libraries = BinaryFormat. Thankfully most builds
don't fail with this because print just isn't used and gets eliminated, dropping
the required dependency in the process. Not all builds are so lucky.
Fix this issue by moving print to the corresponding .cpp file.

This breaks the code which saves and restores LR, so we can't outline
without doing something more complicated for stack adjustment.
Found by inspection; we get lucky in most cases because getMemOpInfo
only handles STRWpost, not any other pre/post-increment forms. But it
hits a couple of artificial testcases in the tree.

As suggested by Fabian on PR37441, use PSHUFLW to extend shift amount types for use with PSRAD/PSRLD to reduce register pressure.
Some of this ideally would be done by combineTargetShuffle but its tricky to do as most of the shuffles are sharing inputs.
