[PATCH] PR target/52137 - bdver2 scheduler needs to be added to bdver1 insn reservations

[Quentin Neill]

Hi,

The patch (http://gcc.gnu.org/bugzilla/attachment.cgi?id=26585)
attached to the bug
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52137) recovers
performance regressions for AMD's bdver2 processor.

It passes bootstrap and make check on x86_64.

The patch is simple and seems to have little risk, therefore AMD would
like to see if this patch can be included in 4.7.0.

Okay to commit to trunk?
