Add MIPS support to perf tools

A long time ago David Daney submitted patches to add MIPS support to perf-tools. Running out of out of time the the series the minor reviewer comments were never dealt with so I now picked up the series and am posting a version 3.

David Daney (3):
MIPS: Add user stack and registers to perf.
perf tools: Add support for MIPS userspace DWARF callchains. perf tools: Hook up MIPS unwind and dwarf-regs in the Makefile
---
v3: Fixed issues raised by Jiri Olsa in the previous version. The short
review thread is archived at
