Several options were incorrectly described, some lacked describing
required arguments while others were simply not documented, fix it.

For perf mem report / perf mem record, pass all unknown options
through to the underlying report/record commands. This makes things
like

perf mem record -a sleep 1

work. Matches how c2c and other tools work.

Adding --ldlat option to specify desired latency for loads event.

Specify 50 as loads event latency:

  $ perf mem record -e ldlat-loads -v --ldlat 50 true
  calling: record -W -d -e cpu/mem-loads,ldlat=50/P true

This patch modifies perf mem to default to sampling loads and stores
simultaneously. It could only do one or the other before yet there was
no hardware restriction preventing simultaneous collection. With this
patch, one run is sufficient to collect both.

It is still possible to sample only loads or stores by using the
-t option:
 $ perf mem -t load rec
 $ perf mem -t load rep
Or
 $ perf mem -t store rec
 $ perf mem -t store rep

The perf report TUI will show one event at a time. The store output will
contain a Weight column which will be empty.

In V2, we updated the man pages to reflect the change and also simplify
the initialization of the argv vector passed to the cmd_*() functions as
per LKML feedback.

In V3, we fixed typos in the changelog.

Clarify in the documentation that 'perf mem report' reports use-latency,
not load/store-latency on Intel systems.

This often causes confusion with users.

This new command is a wrapper on top of perf record and perf report to
make it easier to configure for memory access profiling.

To record loads:
$ perf mem -t load rec .....

To record stores:
$ perf mem -t store rec .....

To get the report:
$ perf mem -t load rep
