pru: Optimize 64-bit logical operations
The earlyclobber in the pattern yields inefficient code due to
unnecessarily generated moves. Optimize by removing the earlyclobber
for two special alternatives:
- If OP2 is a small constant integer.
- If the logical bit operation has only two operands.
gcc/ChangeLog:
* config/pru/pru.md (pru_<code>di3): New alternative for
two operands but without earlyclobber.
gcc/testsuite/ChangeLog:
* gcc.target/pru/bitop-di.c: New test.
