Add mips32 r1 to the list of supported targets for Mips fast-isel 

Summary:
Expand list of supported targets for Mips to include mips32 r1.
Previously it only include r2. More patches are coming where there is 
a difference but in the current patches as pushed upstream, r1 and r2
are equivalent.

Test Plan:
simplestorefp1.ll

add new build bots at mips to test this flavor at both -O0 and -O2
