  [FMV][GlobalOpt] Do not statically resolve non-FMV callers. (#123383)

This fixes a runtime regression in the llvm testsuite:

https://lab.llvm.org/buildbot/#/builders/198/builds/1237

On clang-aarch64-sve2-vla:

predres
        FAIL

A 'predres' version is unexpectedly trapping on GravitonG4. My
explanation is that when the caller in not a versioned function, the
compiler exclusively relies on the command line option, or target
attribute to deduce whether a feature is available. However, there is no
guarantee that in reality the host supports those implied features.

This is a quickfix. We may rather change the mcpu option in the llvm
testsuite build instead.
