H A Dme-debugfs.cae5f3f5b Mon Aug 21 07:24:50 CDT 2017 Aleksandar Markovic <aleksandar.markovic@imgtec.com> MIPS: math-emu: Add FP emu debugfs statistics for branches

Add FP emu debugfs counter for branches.

The new counter is displayed the same way as existing counter, and
its default path is /sys/kernel/debug/mips/fpuemustats/.

The limitation of this counter is that it counts only R6 branch
instructions BC1NEZ and BC1EQZ.
