valgrind-avx512-rollup-fixes-2021Dec29.diff

Rollup fixes to be applied on top of (after) the patches in comments 58, 59 and
60:

* fixes the problem described in comment 67.  The patch set extends
  AMD64Instr::CStore and AMD64Instr::CLoad to also handle 8- and 16- bit
  conditional stores and loads.  However, the emit_AMD64Instr clauses for
  these cases were not correct and still generating 64-bit transactions.  This
  fixes them.  That removes a bunch of incorrect results in regression tests,
  and crashing when running real programs.  The test case avx512-skx is still
  failing, though.

* [trivial fixes] fixes segfaults caused by insufficient alignment in test
  cases avx512-l1.c and avx512-l2.c

* [temporary] disables a few test cases in avx512-l1.c since they don't run on
  my hardware (Core i5-1135G7), even natively.
