Thanks.
Note even 2/3 has a small i386 specific part. Would be good if you
could take a look at that part.

Add builtins/intrinsics for PTWRITE. PTWRITE is a new instruction on Intel
Gemini Lake/
Goldmont Plus that allows to write values into the Processor Trace log. This
allows
very light weight instrumentation of programs.
The intrinsics are compatible to icc. Automatically enable

Add builtins/intrinsics for PTWRITE. PTWRITE is a new instruction on Intel
Cherry Trail
that allows to write values into the Processor Trace log.
This is fairly straight forward, except I had to add isa2 support for variable
number
of operands.
