This patch was already approved in v2. I have included it here because
a) It should not be applied until after the rest of the series, since
the option is useful as long as location_t is 32-bit.
b) The previous version neglected to regenerate common.opt.urls, which I
have corrected here.
-- >8 --
The option -flarge-source-files became unnecessary with 64-bit location_t
and harms performance compared to the new default setting, so silently
ignore it.
gcc/ChangeLog:
* common.opt: Mark -flarge-source-files as Ignored.
* common.opt.urls: Regenerate.
* doc/invoke.texi: Remove -flarge-source-files.
* toplev.cc (process_options): Remove support for
-flarge-source-files.
