I've tried to find main moudle headers where possible, but the TableGen
stuff may warrant someone else looking at it.

; CHECK: [[VAR:[a-z]]]
The problem was that to find the end of the regex var definition, it was
simplistically looking for the next ]] and finding the incorrect one. A
better approach is to count nesting of brackets (taking escaping into
account). This way the brackets that are part of the regex can be discovered
and skipped properly, and the ]] ending is detected in the right place.

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.

is substantially different than a(b|c)d. Form the latter regex instead.
This found a few problems in the testsuite, which serves as its test.

an annoyance of mine when working on tests: if the input .ll file
is broken, opt outputs an error and generates an empty file. FileCheck
then emits its "ooh I couldn't find the first CHECK line, scanning
from ..." which obfuscates the actual problem.

It can pass two tests below on Win32.
- Clang :: CodeGenCXX/dyncast.cpp
- LLVM :: CodeGen/ARM/globals.ll

A CHECK-NOT pattern without a following CHECK pattern simply checks that the
pattern doesn't match before the end of the input file.
You can even have only CHECK-NOT patterns to check that strings appear nowhere
in the input file.
