The attached patch fixes a glicht in the error message generated
for invalid values of enum options. When a "DriverOnly" option
was passed directoy top the compiler, it would still list that as
valid in the error message, e.g. on s390:
$ cc1 <...> -march=native
cc1: error: unrecognized argument in option ‘-march=native’
cc1: note: valid arguments to ‘-march=’ are: g5 g6 native z10 z13 z196 z9-109
z9-ec z900 z990 zEC12
The patched code prints DriverOnly enum values only when the
driver generates the error message.

* opts-common.c (read_cmdline_option): List DriverOnly enum values as
valid only in the error message of the driver, not in the messages of
the language compilers.
