PRU: Fix R3.w0 register class
TI has clarified [1] that R3.w0 is caller saved, so allow compiler to
use it. This is safe change because older GCC versions treat R3.w0 as
fixed register and never use it.

gcc/ChangeLog:
2020-05-05 Dimitar Dimitrov <dimitar@dinux.eu>
* config/pru/pru.h: Mark R3.w0 as caller saved.
gcc/testsuite/ChangeLog:
2020-05-05 Dimitar Dimitrov <dimitar@dinux.eu>
* gcc.target/pru/lra-framepointer-fragmentation-1.c: Update test to
take into account additional available registers.
* gcc.target/pru/lra-framepointer-fragmentation-2.c: Ditto.
