After bc39d7bd (ported to GN in 94c00c10), libclang uses symbol_exports,
and clang/test/LibClang/symbols.test wants the versioned name to be `LLVM_[0-9]$`
instead of `FOO`.

It would be better for CodeMetrics to use hasOneLiveUse while analyzing
static and called once callsites, since inline cost now uses
hasOneLiveUse instead of hasOneUse to avoid overpessimization on dead
constant cases (since this patch https://reviews.llvm.org/D109294).

This change has no noticeable influence now, but it helps improve the
accuracy of cost models of passes that use CodeMetrics.

Currently the X86 shuffle lowering would widen the element type for
shuffle if the mask element value is adjacent. For below example

  %t2 = add nsw <16 x i32> %t0, %t1
  %t3 = sub nsw <16 x i32> %t0, %t1
  %t4 = shufflevector <16 x i32> %t2, <16 x i32> %t3,

  ret <16 x i32> %t4

Compiler would transform the shuffle to
  %t4 = shufflevector <8 x i64> %t2, <8 x i64> %t3,
                      <8 x i64> <i32 8, i32 1, i32 2, i32 3, i32 4,

The current Parser library is solely focused on providing API for
the textual MLIR format, but MLIR will soon also provide a binary
format. This commit renames the current Parser library to AsmParser to
better correspond to what the library is actually intended for. A new
Parser library is added which will act as a unified parser interface
between both text and binary formats. Most parser clients are
unaffected, given that the unified interface is essentially the same as
the current interface. Only clients that rely on utilizing the
AsmParserState, or those that want to parse Attributes/Types need to be
updated to point to the AsmParser library.

[Clang] Fix how we set the NumPositiveBits on an EnumDecl to cover the case of single enumerator with value zero or an empty enum

Currently in Sema::ActOnEnumBody(...) when calculating NumPositiveBits we miss
the case where there is only a single enumerator with value zero and the case of
an empty enum. In both cases we end up with zero positive bits when in fact we
need one bit to store the value zero.

This PR updates the calculation to account for these cases.

We no longer need specialized knowledge of these allocator functions in
this file since we have the correct attributes available now.

As far as I can tell the changes in the attributor tests are due to
things getting more consistent on alloc-family once we remove the static
list entries.

The two test changes in NewGVN merit extra scrutiny: NewGVN appears to
be _extremely_ sensitive to the inaccessiblememonly for reasons that
are beyond me. As a result, I had-enumerated all the attributes on
allocation functions in those two tests instead of using -inferattrs.
I assumed that the two -disable-simplify-libcalls tests there no
longer are sensible since the function declaration now includes all the
relevant attributes.
