f9c4db49bd Add the support code to enable the dwarf accelerator tables. Upcoming patches
to fix the types section (all types, not just global types), and testcases.

The code to do the final emission is disabled by default.

b5dc88b394 Fixed a bug in the code to create a dwarf file and directory table entires when
it is separating the directory part from the basename of the FileName.  Noticed 
that this:

  .file 1 "dir/foo"

when assembled got the two parts switched.  Using the Mac OS X dwarfdump tool
it can be seen easily:

% dwarfdump -a a.out
include_directories[  1] = 'foo'
                Dir  Mod Time   File Len   File Name
                ---- ---------- ---------- ---------------------------
file_names[  1]    1 0x00000000 0x00000000 dir
...

Which should be:
...
include_directories[  1] = 'dir'
                Dir  Mod Time   File Len   File Name
                ---- ---------- ---------- ---------------------------
file_names[  1]    1 0x00000000 0x00000000 foo

64fe093030 First part of support for generating dwarf for assembly source files with the
-g flag.  In this part we generate the .file for the source being assembled and
the .loc's for the assembled instructions.

The next part will be to generate the dwarf Compile Unit DIE and a dwarf
subprogram DIE for each non-temporary label.

Once the next part is done test cases will be added.  rdar://9275556

c551c1c5f9 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.

321335142c Enhance llvm::SourceMgr to support diagnostic ranges, the same way clang does. Enhance
the X86 asmparser to produce ranges in the one case that was annoying me, for example:

test.s:10:15: error: invalid operand for instruction
movl 0(%rax), 0(%edx)
              ^~~~~~~

It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use 
ranges where appropriate if someone is interested.

5a09a8db55 Adding back support for printing operands symbolically to ARM's new disassembler
using llvm's public 'C' disassembler API now including annotations.

Hooked this up to Darwin's otool(1) so it can again print things like branch
targets for example this:
 blx _puts
instead of this:
 blx #-36
and includes support for annotations for branches to symbol stubs like:
 bl	0x40 @ symbol stub for: _puts
and annotations for pc relative loads like this:
 ldr	r3, #8 @ literal pool for: Hello, world!
Also again can print the expression encoded in the Mach-O relocation entries for
things like this:
 movt r0, :upper16:((_foo-_bar)+1234)

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.
