Add support for a new extension to the .file directive:
...
.file filenumber "directory" "filename"
This removes one join+split of the directory+filename in MC internals. Because
bitcode files have independent fields for directory and filenames in debug info,
this patch may change the .o files written by existing .bc files.

Move some ELF directives into ELF asm parser.
...
The .local, .hidden, .internal, and .protected are not legal for all supported
file formats (in particular, they're invalid for MachO). Move the parsing for
them into the ELF assembly parser since that's the format they're for.
Similarly, .weak is used by COFF and ELF, but not MachO, so move the parsing
to the COFF and ELF asm parsers. Previously, using any of these directives
on Darwin would result in an assertion failure in the parser; now we get
a diagnostic as we should.

Rework how the MCWin64EHUnwindInfo instances are stored. Fix issues with

The ChainedParent field had the wrong address, because when the chained unwind

structures, which are now allocated from the MC heap.
