i386: Tweak i386-expand.cc to restore bootstrap on RHEL.
This is a minor change to restore bootstrap on systems using gcc 4.8
as a host compiler. The fatal error is:
In file included from gcc/gcc/coretypes.h:471:0,
from gcc/gcc/config/i386/i386-expand.cc:23:
gcc/gcc/config/i386/i386-expand.cc: In function 'void ix86_expand_fp_absneg_operator(rtx_code, machine_mode, rtx_def**)':
./insn-modes.h:315:75: error: temporary of non-literal type 'scalar_float_mode' in a constant expression
#define HFmode (scalar_float_mode ((scalar_float_mode::from_int) E_HFmode))
^
gcc/gcc/config/i386/i386-expand.cc:2179:8: note: in expansion of macro 'HFmode'
case HFmode:
^
The solution is to use the E_?Fmode enumeration constants as case values
in switch statements.

* config/i386/i386-expand.cc (ix86_expand_fp_absneg_operator):
Use E_?Fmode enumeration constants in switch statement.
(ix86_expand_copysign): Likewise.
(ix86_expand_xorsign): Likewise.
