7143d73e96 reject attempts to use ()'s in patterns, these are reserved for filecheck.

2b1f7c6a75 reimplement the regex matching strategy by building a single 
regex and matching it instead of trying to match chunks at a time.
Matching chunks at a time broke with check lines like 
  CHECK: foo {{.*}}bar
because the .* would eat the entire rest of the line and bar would
never match.

Now we just escape the fixed strings for the user, so that something
like:
  CHECK: a() {{.*}}???
is matched as:
  CHECK: {{a\(\) .*\?\?\?}}
transparently "under the covers".

97cf81c3c6 Use CanonicalizeInputFile to canonicalize the entire buffer containing the 
CHECK strings, instead of canonicalizing the patterns directly.  This allows
Pattern to just contain a StringRef instead of std::string.

b8a623820a lit: When executing shell scripts internally, don't allow piped stderr on any 
commands except the last one, instead redirect the stderr to a temporary

06695b3ea1 Add a magic LLVM_DISABLE_CRT_DEBUG environment variable which we check in RegisterHandler and use to disable the Win32 crash dialogs. These are a major blocker to any kind of automated testing.

b9aca1a178 remove DebugLoc from MCInst and eliminate "Comment printing" from 
the MCInst path of the asmprinter.  Instead, pull comment printing
out of the autogenerated asmprinter into each target that uses the
autogenerated asmprinter.  This causes code duplication into each
target, but in a way that will be easier to clean up later when more
asmprinter stuff is commonized into the base AsmPrinter class.

This also fixes an xcore strangeness where it inserted two tabs
before every instruction.

2a098581a8 Fix a subtle bug in "return;" generation which caused us to miss 
a return in one case.  Instead of sprinking return handling code
throughout the asmprinter generator, just treat it like any other
normal statement.

52651f7623 hoist the call to processDebugLoc out of the generated 
asm printer into the "printInstruction" routine.  This
fixes a problem where the experimental asmprinter would
drop debug labels in some cases, and fixes issues on ppc/xcore
where pseudo instructions like "mr" didn't get debug locs properly.

It is annoying that this moves the call from one place into each
target, but a future set of more invasive refactorings will fix
that problem.
