i386: Fix up TARGET_QIMODE_MATH for many AMD CPU tunings [PR98957]
As written in the PR, TARGET_QIMODE_MATH was meant to be set for all
tunings and it was the case for GCC <= 7, but as the number of
PROCESSOR_* enumerators grew, some AMD tunings (which are at the end
of the list) over time got enumerators with values >= 32 and
TARGET_QIMODE_MATH became disabled for them, in GCC 8 for 2
tunings, in GCC 9 for 7 tunings, in GCC 10 for 8 tunings, and
on the trunk for 11 tunings.
The following patch fixes it by using uhwis rather than uints
and gives them also symbolic names.
