float<QHI:mode><FP_ISA3:mode>2_internal uses gen_extendhidi2 on a VSX
register but extendhidi2 only supports GPRs if -mno-gen-cell-microcode
is in effect. Fixed by adding a check of TARGET_VSX_SMALL_INTEGER.
Bootstrap/regtest on powerpc64le-linux with no regressions, ok for
trunk? The -mvsx-small-integer option/code was introduced in GCC 7 so no
need for backport.
