perf annotate: Add 'ret' (intel disasm style) as an alias for 'retq'
When we use the 'intel' disassembler style we get 'ret' instead of
'retq', so add that as an alias.
# perf annotate --disassembler-style=intel --stdio2 acpi_processor_ffh_cstate_enter > before
Apply this patch and then:
# perf annotate --disassembler-style=intel --stdio2 acpi_processor_ffh_cstate_enter > after
# diff -u before after
