PR target/97250: i386: Add support for x86-64-v2, x86-64-v3, x86-64-v4 levels for x86-64
These micro-architecture levels are defined in the x86-64 psABI:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/commit/77566eb03bc6a326811cb7e9
PTA_NO_TUNE is introduced so that the new processor alias table entries
do not affect the CPU tuning setting in ix86_tune.
The tests depend on the macros added in commit 92e652d8c21bd7e66cbb0f900
("i386: Define __LAHF_SAHF__ and __MOVBE__ macros, based on ISA flags").
