[Bug target/28158] New: ICE on complex operation with -O1 -msse

["fxcoudert at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following Fortran testcase exhibits a failure with -O(>=1) -msse:

$ cat foo.f90
     subroutine yhalf(z)
     complex cdexpj,z
     z=cdexpj((0.d0,1.d0)*z)
     end
$ gfortran -c -O3 -msse -mfpmath=sse,387   foo.f90
foo.f90: In function ?yhalf?:
foo.f90:3: error: unrecognizable insn:
(insn 13 12 14 3 (set (reg:DF 63)
        (neg:DF (reg:DF 62))) -1 (nil)
    (nil))
foo.f90:3: internal compiler error: in extract_insn, at recog.c:2077
Please submit a full bug report,
with preprocessed source if appropriate.

$ gfortran -c -O3 -msse2 -mfpmath=sse,387   foo.f90
