Anshuman Khandual 030099bc91 perf: Add irq and exception return branch types ...

[ Upstream commit cedd3614e5 ]

This expands generic branch type classification by adding two more entries
there in i.e irq and exception return. Also updates the x86 implementation
to process X86_BR_IRET and X86_BR_IRQ records as appropriate. This changes
branch types reported to user space on x86 platform but it should not be a
problem. The possible scenarios and impacts are enumerated here.
