Hi,
This patch adds march for broadwell cpu.
-march=bdw is the same as -march=core-avx2 but with support for rdseed,
adcx, prefetchw. OK for trunk?
Thanks.

* config.gcc: Support march=bdw.
* config/i386/driver-i386.c (host_detect_local_cpu): Detect broadwell.
* config/i386/i386.c (ix86_option_override_internal): Add bdw.
* doc/invoke.texi: Document march=bdw.
