Fix pr101384-1.c code generation test.
Add support for the compiler using XXSPLTIB reg,255 to load all 1's into a
register on power9 and above instead of using VSPLTI{B,H,W} reg,-1.

Patch to fix the code generation test for power9 and power10.
The previous patch posted was the wrong patch.
This patch fixes the regexp in pr101384-1.c to add support for power9 and
power10 using XXSPLTIB to set a vector register to all 1's instead of
VSPLTIS{B,H,W} that power8 generates.

Patch to update code generation test
The test wants to load all 1's into a vector register. On power8 it uses
VSPLTIS{B,H,W} to load up the value. On power9 and power10, it uses XXSPLTIB
to load up the value. This patch checks for XXSPLTIB being generated.

On power9 and power10 it uses xxspltib to load it up.
