xtensa: The use of CLAMPS instruction also requires TARGET_MINMAX, as well as TARGET_CLAMPS
Because both smin and smax requiring TARGET_MINMAX are essential to the
RTL representation.
gcc/ChangeLog:
* config/xtensa/xtensa.cc (xtensa_match_CLAMPS_imms_p):
Simplify.
* config/xtensa/xtensa.md (*xtensa_clamps):
Add TARGET_MINMAX to the condition.
