Subject: [PATCH] Revert "Move popcount and hamdist back from z14 to z13 after needed edits."

This reverts commit d4f5fca6a1e8ceb3bda243e5a7afcc8762025f84.

Unfortunately not only the extended mnemonics are not available with z13,
but also vpopct M3=1-3 is reserved. Thus you'll get an illegal-instruction
if run on z13 as vector enhancement facility 1 (introduced with z14) is
not available.

This is recognized with test-fails if run on z13:
FAIL: t-bin
FAIL: t-fac_ui
FAIL: t-mfac_uiui
FAIL: t-primorial_ui
FAIL: t-hamdist
FAIL: t-popcount
FAIL: t-nextprime
