INST_RETIRED.ANY is -e rc0. ICACHE.MISSES is r280.
Note that except for a few, the performance counters are processer specific.
The full list of available counters is found in "Intel® 64 and IA-32
Architectures Software Developer’s Manual Volume 3B: System Programming Guide,
Part 2". Eg. the ones for Sandy Bridge are found in section 19.4:
http://www.intel.com/content/www/us/en/processors/architectures-software-developer-manuals.html
(For example, ICACHE.MISSES is umask=0x02 and eventnum=0x80, hence r280.)
