[X86] AMD Zen 3: cap LoopMicroOpBufferSize to workaround PR50384 (quadratic IndVars runtime)
While i would like to keep the right value here,
i would also like to be able to actually compile
e.g. vanilla test-suite.
256 is a pretty random guess, it should be pretty good enough
for serious loops, but small enough to result in tolerant
compile times for certain edge cases.
