Martin Storsjö 3125af2b6b [compiler-rt] [test] [profile] Avoid issues with an implicit .exe suffix
Mingw toolchains implicitly add an .exe suffix if the output linked
file doesn't have a suffix. In many cases the extra suffix doesn't
cause any issues, but in some tests, this discrepancy between expected
output file name and actual output file does affect the tests.

In one test, a rm command fails to remove the executable since it
doesn't have the expected name. By failing to remove the executable, the
later llvm-profdata command tries to read the executable as if it was
a profile data file.

In another test, when the Python executor executes commands, it can
resolve executable names without the extra .exe suffix for absolute
paths (when most binaries are executed as e.g. "%t/foo"), but it fails
to resolve the executables for relative paths such as "./foo". Making
the paths absolute by using %t here shouldn't affect what the test tries
to validate.
