recompute opt flags after opt level change
flag_omit_frame_pointer is set in machine-independent code depending
on the optimization level. It is then overridden in x86
target-specific code depending on a macro defined by
--enable-frame-pointer.
Uses of attribute optimize go through machine-independent overriding
of flag_omit_frame_pointer, but the x86-specific overriding code did
NOT cover this flag, so, even if the attribute does not change the
optimization level, flag_omit_frame_pointer may end up with a
different value, and prevent inlining because of incompatible flags,
as detected by the gcc.dg/ipa/iinline-attr.c test on an
--enable-frame-pointer x86 toolchain.
