Fix issues with Windows dump_syms_unittest

* Turn DumpSymsRegressionTest into a parameterized test so it's easier to
see which test file is failing

* Convert dump_syms_regtest.sym to DOS line endings, being careful to
preserve the required spaces at the end of 'STACK WIN' lines

* In test #4 (omap_reorder_bbs), since the .exe corresponding to the .pdb is
not present, no INFO line is generated in the .sym file.  Update .sym file.

* Stop collecting stderr from dump_syms.  Future work: perhaps it's worth
collecting stderr to compare with a different file to verify that "Couldn't
locate EXE or DLL file" is output when expected?

* Regenerate testdata for test #5 (dump_syms_regtest64), which currently
does not pass, seemingly due a mis-match in the PDB age between the .pdb
file and the .sym file.  Also add the .exe corresponding to the .pdb
present, to provide CFI
