IRA patch: Handle attribute "enabled"

Subject: IRA patch: Handle attribute "enabled"

While experimenting with an ARM/NEON patch that tries to conditionally
add "?" constraint modifiers on some patterns using attribute "enabled",
I noticed that this did not cause IRA to change register allocation.
Fixed by this patch.

Tested on i686-pc-linux-gnu using the CodeSourcery build/test scripts
which I think involves a bootstrap.  Ok?
