compilerplugins: try to make these work with icecream
There are some problems here, this should fix one of them: the
getFilename function returns "<stdin>" for spelling locations, because
the input to clang is sort of preprocessed via -frewrite-includes if
icecream is used and the file is built on a remote host (whereas it's
apparently not preprocessed if the file is compiled locally by icecream).
Using getPresumedLoc() uses the #line directives in the preprocessed
input, which avoids the problem but is more expensive, so try to use it
only when necessary.
The getFileEntry(getMainFileID())->getName() pattern will also result
in "<stdin>", but fortunately icecream passes -main-file-name,
which oddly enough isn't used by the SourceManager's spelling locations,
but is available separately via CodeGenOptions.
This builds everything successfully with clang version 6.0.0:
ICECC_PREFERRED_HOST=myremote make check gb_SUPPRESS_TESTS=t
