Add a new interface __sanitizer_get_report_path which will return the
full path to the report file if __sanitizer_set_report_path was
previously called (otherwise it returns null). This is useful in
particular for memory profiling handlers to access the path which
was specified at compile time (and passed down via
__memprof_profile_filename), including the pid added to the path when
the file is opened.
There wasn't a test for __sanitizer_set_report_path, so I added one
which additionally tests the new interface.

Split out of D89086 as suggested.
Change the default of the log_path flag to nullptr, and the code
consuming that flag (ReportFile::SetReportPath), to treat nullptr as
stderr (so no change to the behavior of existing users). This allows
code to distinguish between the log_path being specified explicitly as
stderr vs the default.
This is so the flag can be used to override the new report path variable
that will be encoded in the binary for memprof for runtime testing.

See https://reviews.llvm.org/D58620 for discussion, and for the commands
I ran. In addition I also ran
for f in $(svn diff | diffstat | grep .cc | cut -f 2 -d ' '); do rg $f . ; done
and manually updated (many) references to renamed files found by that.
