Joel E. Denny dc5ba317b1 [FileCheck] Implement -v and -vv for tracing matches
-v prints all directive pattern matches.

-vv additionally prints info that might be noise to users but that can
be helpful to FileCheck developers.

To maximize code reuse and to make diagnostics more consistent, this
patch also adjusts and extends some of the existing diagnostics.
CHECK-NOT failures now report variables uses.  Many more diagnostics
now report the check prefix and kind of directive.

Daniel Sanders fd557cb01f [FileCheck] Add --check-prefixes as a shorthand for multiple --check-prefix options.
Summary:
This new alias takes a comma separated list of prefixes which allows
'--check-prefix=A --check-prefix=B --check-prefix=C' to be written as
'--check-prefixes=A,B,C'.

Daniel Sanders 43b5f572fa FileCheck: fix a bug with multiple --check-prefix options. Similar to r194565
Summary:
Directives are being ignored, when they occur between a partial-word false
match and any match on another prefix.

For example, with FOO and BAR prefixes:
   _FOO
   FOO: foo
   BAR: bar
FileCheck incorrectly matches:
   fog
   bar

This happens because FOO falsely matched as a partial word at '_FOO' and was
ignored while BAR matched at 'BAR:'. The match of BAR is incorrectly returned
as the 'first match' causing the FOO directive to be discarded.

Fixed this the same way as r194565 (D2166) did for a similar test case.
The partial-word false match should be counted as a match for the purposes of
finding the first match of a prefix, but should be returned as a false match
using CheckTy::CheckNone so that it isn't treated as a directive.

Fixes PR17995
