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.

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".
