Summary:
This simplifies the code and moves everything to tablegen for consistency. This
also prepares the ground for adding issue counters.

Summary:
The pfm counters are now in the ExegesisTarget rather than the
MCSchedModel (PR39165).
This also compresses the pfm counter tables (PR37068).

rL342465 is breaking the MSVC buildbots, but I need to revert this dependent revision as well.

Summary:
The snippet-generation part goes to the SnippetGenerator class.
This will allow benchmarking arbitrary code (see PR38437).

Summary:
This allows targets to override code generation for some instructions.
As an example of override, this also moves ad-hoc instruction filtering
for X86 into the X86 ExegesisTarget.
