Michael J. Spencer de3a2118db MC/X86/COFF: Allow quotes in names when targeting MS/Windows, 
as MC is the only assembler we support.

This splits MS/Windows and GNU/Windows ASM infos into two seperate classes.
While there is currently only one difference, full MS C++ ABI support will
require many more.

Owen Anderson 0ca562ec4c Teach the MC to output code/data region marker labels in MachO and ELF modes. These are used by disassemblers to provide better disassembly, particularly on targets like ARM Thumb that like to intermingle data in the TEXT segment.

Benjamin Kramer 6397051ece Don't drop alignment info on local common symbols. 
- On COFF the .lcomm directive has an alignment argument.
- On ELF we fall back to .local + .comm

Based on a patch by NAKAMURA Takumi.

Fixes PR9337, PR9483 and PR10128.

Chris Lattner 324c86600d eliminate the magic AbsoluteDebugSectionOffsets MAI hook, 
which is really a property of the section being referenced.
Add a predicate to MCSection to replace it.

Yay for reduction in magic.

Chris Lattner e239fa05cd isAbsoluteEHSectionOffsets always returns false, eliminate it 
and substitute false at the one call site.

Chris Lattner fc2e376a15 use EmitLinkage for functions as well as globals. One output 
change is that we now use ".linkonce discard" for global variables
instead of ".linkonce samesize".  These should be the same, just less
strict.  If anyone is interested in mcizing MCSection for COFF targets,
this should be easy to fix.

Chris Lattner ff234e09b9 Eliminate SetDirective, and replace it with HasSetDirective. 
Default HasSetDirective to true, since most targets have it.

The targets that claim to not have it probably do, or it is
spelled differently. These include Blackfin, Mips, Alpha, and
PIC16.  All of these except pic16 are normal ELF targets, so
they almost certainly have it.

Chris Lattner 2b4364fe03 revert 93934, removing the MCAsmInfo endianness bit. I can't 
stomache MCAsmInfo having this, and I found a better solution to
this layering issue.

Chris Lattner 003b5c8472 give MCAsmInfo a 'has little endian' bit. This is unfortunate, but 
I really want clients of the streamer to be able to say "emit this
64-bit integer" and have it get broken down right by the streamer.

I may change this in the future, we'll see how it works out.
