This adds support for "func@localentry", an expression that returns the
ELFv2 local entry point address of function "func". I've excluded
dynamic relocation support because that obviously would require glibc
changes.

* config/tc-ppc.c (md_assemble): Move code adjusting reloc types
later. Merge absolute and relative branch reloc selection.
Generate 16-bit relocs for most 16-bit insn fields given a
non-constant expression.
The XCOFF assembler does some wierd things with instructions like
`lwz 9,sym(30'. See the comment in md_apply_fix. From an ELF
perspective, it's weird even to magically select a TOC16 reloc
when a symbol is in the TOC/GOT. ELF assemblers generally use
modifiers like @toc to select relocs, so remove this "feature"
for ELF. I believe this was to support gcc -m32 -mcall-aixdesc
but that combination of gcc options has been broken for a long
time.
* config/tc-ppc.c (ppc_is_toc_sym): Remove OBJ_ELF support.

The purpose of this patch is to provide a way for one object file

Since regzmm can't be used in AVX2 gather instructions, there is no need

This is to avoid expressions like: %hi(foo) + 1, which will
not do what you expect. The complex relocations can handle it,
but the internal fixups can't.
The direct rounding floating-point VCVT instructions introduced in

These files are source files and have no business being +x. We couldn't
