perf, x86: Implement simple LBR support
Implement simple suport Intel Last-Branch-Record, it supports all
hardware that implements FREEZE_LBRS_ON_PMI, but does not (yet) implement
the LBR config register.
The Intel LBR is a FIFO of From,To addresses describing the last few
branches the hardware took.
This patch does not add perf interface to the LBR, but merely provides an
interface for internal use.
