eec96958cd implement and document support for filecheck variables. This 
allows matching and remembering a string and then matching and
verifying that the string occurs later in the file.

Change X86/xor.ll to use this in some cases where the test was
checking for an arbitrary register allocation decision.

81f46d9ce1 remove support for "NoSub" from regex. It seems like a minor optimization 
and makes the API more annoying.  Add a Regex::getNumMatches() method.

5d6a05f4d4 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".

2702e6aa53 special case Patterns that are a single fixed string. This is a microscopic 
perf win and is needed for future changes.

528700863a add and document regex support for FileCheck. You can now do stuff like: 
; CHECK: movl {{%e[a-z][xi]}}, %eax

or whatever.

adea46ed61 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.

7bee3271e8 rewrite FindStringInBuffer to use an explicit loop instead of 
trying to wrap strstr which is just too inconvenient.  Make it
use a StringRef to avoid ".c_str()" calls.

88a7e9ee8d make filecheck default to canonicalizing horizontal whitespace 
away.  This way you can write a space and it matches arbitrary spaces and tabs.
