Remove the superfluous section name quotes, and combine the longs into a
single command.
Before:
911: .pushsection ".discard.annotate_insn", "M", @progbits, 8; .long 911b - .; .long 2; .popsection
After:
911: .pushsection .discard.annotate_insn, "M", @progbits, 8; .long 911b - ., 2; .popsection
No change in functionality.

Remove newlines and tabs from the annotation macros so the invoking code
can insert them as needed to match the style of the surrounding code.

Consolidate __ASM_ANNOTATE into a single macro which is used by both C
and asm. This also makes the code generation a bit more palatable by
putting it all on a single line.
Turn this:
911:
.pushsection .discard.annotate_insn,"M", @progbits, 8
.long 911b - .
.long 1
.popsection
jmp __x86_return_thunk
Into:
911: .pushsection ".discard.annotate_insn", "M", @progbits, 8; .long 911b - .; .long 1; .popsection
jmp __x86_return_thunk

In preparation for the objtool klp diff subcommand, add an
ANNOTATE_DATA_SPECIAL macro which annotates special section entries so
that objtool can determine their size and location and extract them
when needed.

In preparation for using the objtool annotation macros in higher-level
objtool.h macros like UNWIND_HINT, move them to their own file.
