Florian Weimer 815233f54b x86: Skip XSAVE state size reset if ISA level requires XSAVE 
If we have to use XSAVE or XSAVEC trampolines, do not adjust the size
information they need.  Technically, it is an operator error to try to
run with -XSAVE,-XSAVEC on such builds, but this change here disables
some unnecessary code with higher ISA levels and simplifies testing.

Related to commit befe2d3c4d
("x86-64: Don't use SSE resolvers for ISA level 3 or above").
