Add initial MIPS support
Supports perf reports from MIPS targets.
MIPS/perf isn't really supported on the mainstream Linux kernel, but
there are a number of patches around which can be used to build
working perf support:
https://lkml.org/lkml/2016/4/1/162
This change just adds the definitions required by hotspot to
support this.
