eb4399962e [ms-inline asm] Add support for lexing hexidecimal integers with a [hH] suffix.

a490793037 Use the new script to sort the includes of every file under lib.
Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.

Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

79d6f55f89 Add support for macro parameters/arguments delimited by spaces,
to improve compatibility with GNU as.

Based on a patch by PaX Team.

Fixed assertion failures on non-Darwin and added additional test cases.

00e28bee78 Handle missing newline at EOF more gracefully in MC AsmLexer.
If we see an EOF w/o a preceding end-of-line, return an EndOfStatement
token before returning the Eof token.

Based on patch by Stepan Dyatkovskiy.

4a91571f82 First step in supporting #line directives in assembler. This step parses the
#line directives with the needed support in the lexer.  Next will be to build
a simple file/line# table mapping source SMLoc's for later use by diagnostics.
And the last step will be to get the diagnostics to use the mapping for file
and line numbers.

213800d44b Clean up assembly statement separator support.
The MC asm lexer wasn't honoring a non-default (anything but ';') statement
separator. Fix that, and generalize a bit to support multi-character
statement separators.

CurPtr[0] == '\n' when testing the character after a "0b" when looking
to see if it part of a something like "jmp 0b".

438a36f66a Fixed the problem with a branch to "0b" that was not parsed by llvm-mc
correctly.  The Lexer was incorrectly eating the newline casusing it to branch
to address 0.  Updated the test case to use a "0:" label and a branch to "0b".

a3731b17c0 Revert r103137, fix for $ in labels. It looks like we can't actually handle this
at the token level. Consider the following horrible test case:

  a = 1
  .globl $a
  movl ($a), %eax
  movl $a, %eax
  movl $$a, %eax

124dc743bc implement mc asmparser support for '.', which gets the
current PC.  rdar://7834775

We now produce an identical .o file compared to the cctools
assembler for something like this:

_f0:
L0:
        jmp L1
        .long . - L0
L1:
        jmp A
        .long . - L1
