Add -M option to report/annotate to pass directly to objdump.  This
allows to use -M intel for intel style disassembler syntax, which is
useful for people who are very used to the Intel syntax.

If you have --symfs in perf report, then you also need it for perf
annotate.  This allows off-box assembly level analysis of perf.data
samples.

This patch complements:

<title>perf annotate: Make output more readable</title>

<content type='text'>
This patch adds two new options to perf annotate:
	- --no-asm-raw : Do not display raw instruction encodings
	- --no-source  : Do not interleave source code with assembly code

We believe those options make the output of annotate more readable.

Systematically displaying source can make it hard to follow code and
especially optimized code.

Raw encodings are not useful in most cases.

<title>perf report/annotate/script: Add option to specify a CPU range</title>

<id>5d67be97f8903d05ce53597fb5f3bc25a45e8026</id>
<content type='text'>
Add an option to perf report/annotate/script to specify which
CPUs to operate on. This enables us to take a single system wide
profile and analyse each CPU (or group of CPUs) in isolation.

This was useful when profiling a multiprocess workload where the
bottleneck was on one CPU but this was hidden in the overall
profile. Per process and per thread breakdowns didn't help
because multiple processes were running on each CPU and no
single process consumed an entire CPU.

The patch converts the list of CPUs returned by cpu_map__new
into a bitmap for fast lookup. I wanted to use -C to be
consistent with perf top/record/stat, but unfortunately perf
report already uses -C &lt;comms&gt;.

 v2: Incorporate suggestions from David Ahern:
	- Added -c to perf script
	- Check that SAMPLE_CPU is set when -c is used
	- Update documentation

 v3: Create perf_session__cpu_bitmap()

Relying just on ~/.perfconfig or rebuilding the tool disabling support
for the TUI is too cumbersome, so allow specifying which UI to use and
make the command line switch override whatever is in ~/.perfconfig.
