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).

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.

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.

Add asserts that verify that the memory accesses of a new copy statement
are defined for all domain instances the copy statement is defined for.

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.

It currently fires an assert if you even try. Looking back, I don't think it ever worked because it only changed the name of the function object, but not the intrinsic ID stored in it. Given that, I think it can be removed since no one has noticed or complained in the past 4 years.

This change fixes a bug that was introduced by r285851.
r285851 converted .interp section as an output section to an input
section. But I forgot to make it a "Live" section, so if -gc-section
is given, it was garbage collected.

This Makes sure we only export targets that we're distributing, since
cmake will fail to import the file otherwise due to missing targets.

Summary: IsExpensiveToCopy can return false positives for incomplete types, so ignore them.
All existing ClangTidy tests that depend on this function still pass as the types are complete.

This replaces every occurrence of _LIBCPP_STD_VER in the tests with
TEST_STD_VER. Additionally, for every affected
file, #include "test_macros.h" is being added explicitly if it wasn't
already there.
