Adding support for name term being specified within
the alias definition and gives the name for the alias.
Alias could be now defined like:
name=BR_MISP_EXEC.ALL_BRANCHES,event=0x89,umask=0xff
It'll be handy for having single file with multiple
alias definitions.

Adding support to parse non architectural event aliases
for given cpu. These aliases will be provided as single
files parsed by pmu_aliases_parse_multi function.

Currently the -C option does not work for record command,
because of the targets mismatch when synthesizing threads.
Fixing this by using proper target interface for the
synthesize decision.

Making the attr test script runner to pass proper
verbose option. Also making single '-v' be more
reader friendly and display just the test name.
Making the current output to be display for '-vv'.

Make attr script to check for 'cpu' when testing
event properties. This will allow us to check the
'-C X' option for both record and stat commands.

precise modifier on 'instructions' event on SandyBridge and
