Rui Ueyama 7163027884 Move code to emit error messages from Filesystem.cpp to Driver.cpp.
isFileWritable() checked if a file is writable and then emitted
an error message if it is not writable. So it did more than the
name says. This patch moves error() calls to Driver.

James Henderson b7a90ef48e [ELF] Fail the link early if the map file path is invalid
As with the changes made in r297645, we do not want a potentially long link to
be run, if it will ultimately fail because the map file is not writable. This
change reuses the same functionality as the output file path check. See
https://reviews.llvm.org/D30449 for further justification and explanations.
