Resubmit "Add pdb-diff test."
This was originally reverted because of two issues.
1) Printing ANSI color escape codes even when outputting to
a file
2) Module name comparisons were failing when comparing a PDB
generated on one machine to a PDB generated on another
machine.
I attempted to fix #2 by adding command line options which let
you specify prefixes to strip from the beginning of embedded
paths, which effectively lets us specify a path to "base" each
PDB from and only compare the parts under the base. But this is
tricky because PDB paths always use Windows path syntax, even
when they are created on non-Windows hosts. A problem still
existed when constructing the prefix to strip, where we were
accidentally using a host-specific path separator instead of
a Windows path separator.
This resubmission fixes the issue on Linux (and I have verified
that the test now passes on Linux).

This test verifies that we produce PDBs compatible with MSVC in various ways.
|
||||
We check in a cl-generated object file, PDB, and original source which serve
|
||||
as the "baseline" for us to measure against. Then we link the same object
|
||||
file with LLD and compare the two PDBs. Since the baseline object file and
|
||||
PDB are already checked in, we just run LLD on the object file.
|
||||

||||
