82e15e4544 Handle recursive variable definitions directly. This gives us better error 
messages and allows us to fix PR11865.

9c7eec9282 The error check for using -g with a .s file already containing dwarf .file 
directives was in the wrong place and getting triggered incorectly with a
cpp .file directive.  This change fixes that and adds a test case.

2d545fa143 Split Finish into Finish and FinishImpl to have a common place to do end of 
file error checking. Use that to error on an unfinished cfi_startproc.

The error is not nice, but is already better than a segmentation fault.

2ea569c7e0 test/MC/AsmParser/2011-09-06-NoNewline.s: Add explicit -mtriple=i386. It uses X86 instruction.

FIXME: Why run llvm-mc as the same input by 3 times?

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.

2f728674cf 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.

88387d64d6 Asm parser range checking on .<size> <value> directives. 
For example, ".byte 256" would previously assert() when emitting an object
file. Now it generates a diagnostic that the literal value is out of range.

0021487a8e Test .seh_startchained and .seh_endchained parsing. 
Rework how the MCWin64EHUnwindInfo instances are stored. Fix issues with
chained unwind areas exposed by the test that were related to this.

The ChainedParent field had the wrong address, because when the chained unwind
info was added, the addresses shifted around. Now we store the pointers to the
structures, which are now allocated from the MC heap.

ede0f07dae Add tests for .seh_setframe and .seh_handlerdata parsing. Fix issues with 
them.

I had to add a special SwitchSectionNoChange method to MCStreamer just for
.seh_handlerdata. If this isn't OK, please let me know, and I'll find some
other way to fix .seh_handlerdata streaming.

e7be1f2990 Revert r125595, which is an X86-only undocumented assembly syntax extension 
enabled for all targets. Non-X86 targets should not have this behavior
enabled by default.

Joerg, if you would like to resubmit with the behavior conditionalized to be
X86-ELF only, that's fine.
