[X86] Add a few more fptoui test cases to the vec_fp_to_int.ll. The codegen for these test cases will be improved for AVX512 in a future commit.

Summary:
This kill various depreacated API related to attribute :
 - The deprecated C API attribute based on LLVMAttribute enum.
 - The Raw attribute set format (planned to be removed in 4.0).

llvm-svn: 286062

Patch switches computing of --build-id hash to tree.

This is the way when input data is splitted by chunks,
hash is computed for each one in threaded/non-threaded way.
At the end hash is conputed for result tree.

With or without -threads the result hash is the same.

Summary:
Fixes PR30869.

In D25977 I meant to change all functions that care about lifetime. I
changed constructors, factory functions, but I missed member/free
functions that return new instances. This patch changes them.

[AVX-512] Add avx512vl command line to the fpext test and add -show-mc-encoding to show where we aren't using EVEX instructions.

llvm-svn: 286058

[AVX-512] Lower AVX cvtpd2ps intrinsic to ISD::FP_ROUND so it can use EVEX instruction when available.

llvm-svn: 286057

[AVX-512] Lower SSE/AVX cvtdq2ps intrinsics directly to ISD::SINT_TO_FP so they can use EVEX instructions when available.

llvm-svn: 286056

[AVX-512] Add -show-mc-encoding to legacy vector intrinsic tests so we can see when VEX or EVEX encoded instructions are being emitted. Make sure the tests all have an avx2 command line and an skx command line.

A CommonInputSection is a section containing all common symbols.
That was an input section but was abstracted in a different way
than the synthetic input sections because it was written before
the synthetic input section was invented.

This patch rewrites CommonInputSection as a synthetic input section
so that it behaves better with other sections.

In short the patch introduces support for linking object file conform
MIPS N32 ABI [1]. This ABI is similar to N64 ABI but uses 32-bit
pointer size.

The most non-trivial requirement of this ABI is one more relocation
packing format. N64 ABI puts multiple relocation type into the single
relocation record. The N32 ABI uses series of successive relocations
with the same offset for this purpose. In this patch, new function
`mergeMipsN32RelTypes` handle this case and "convert" N32 relocation to
the N64 relocation so the rest of the code keep unchanged.

For now, linker does not support series of relocations applied to sections
without SHF_ALLOC bit. Probably later I will add the support or insert
some sort of assert into the `relocateNonAlloc` routine to catch this
case.

Previously, we do this piece of code to iterate over all input sections.

  for (elf::ObjectFile<ELFT> *F : Symtab.getObjectFiles())
    for (InputSectionBase<ELFT> *S : F->getSections())

It turned out that this mechanisms doesn't work well with synthetic
input sections because synthetic input sections don't belong to any
input file.

This patch defines a vector that contains all input sections including
synthetic ones.

Summary:
SmallSetVector uses DenseSet, but that means we need to reserve some
values for the empty and tombstone keys.

It seems to me we should have a general way to let us store full-range
ints inside of DenseSets, and furthermore that we probably shouldn't
silently let you add ints into DenseSets without explicitly promising
that they're in range.  But that's a battle for another day; for now,
just fix this code, since we currently do something Very Bad when
compiling ffmpeg.

Fixes PR30914.

We are repeatedly calling computeZeroableShuffleElements in many shuffle lowering calls for the same shuffle mask/inputs.

This is a first step towards reusing the zeroable result, initially just for lowerVectorShuffleAsShift calls.

This is just the basic separation, without any cleanup. Further changes
