  Log Message:
  -----------
  [ARM] Prevent use of the VFP calling convention when +soft-float is enabled (#221434)

This check was implemented in #111334 for -fpregs and Thumb1 cases, but
+soft-float is a distinct case that can lead to the same silent calling
convention mismatches.

Fix tests that were using +soft-float and the VFP calling convention.

Clarify comment about hard-float support on mve+nofp cores.
