[PowerPC] Stop defining _ARCH_PWR6X on POWER7 and up
Summary:
The predefined macro `_ARCH_PWR6X` is associated with GCC's
`-mcpu=power6x` option, which enables generation of P6 "raw mode"
instructions such as `mftgpr`.
Later POWER processors build upon the "architected mode", not the raw
one. `_ARCH_PWR6X` should not be defined for these later processors.
Fixes PR#40236.
