Restrict a VSX extract to TARGET_POWERPC64 (PR88213)
This pattern optimises a scalar extract from a vector loaded from
memory to be just a scalar load from memory. But to do a 64-bit
integer load you need 64-bit integer registers, which needs
TARGET_POWERPC64.
PR target/88213
* config/rs6000/vsx.md (*vsx_extract_<P:mode>_<VSX_D:mode>_load):
Require TARGET_POWERPC64.
