[PATCH v5 0/7] Event parsing fixes

[James Clark]

I rebased this one and made some other fixes so that I could test it,
so I thought I'd repost it here in case it's helpful. I also added a
new test.

But for the testing it all looks ok.

There is one small difference where it now hides _all_ <not supported>
events, when previously it would only hide some selected subset of
events like "stalled-cycles-frontend". I think this is now more
consistent across platforms because, for example, Apple M only has
cycles and instructions, and the rest of the default events would
always show as <not supported> there.

Tested on Raptor Lake, Juno, N1, Ampere (with the DSU cycles PMU) and
I also faked an Apple M on Juno. 

Changes since v4:

  * Hide all <not supported> default events when not verbose
  * Remove previous note about <not supported> behavior from the cover
    letter and replace it with a new note about the new behavior
 
Changes since v3:

  * Rebase onto perf-tools-next 6236ebe07
  * Fix Intel TPEBS counting mode test
  * Fix arm-spe build
  * Add support for DT devices in stat test
  * Add a new test for hybrid perf stat default arguments
