[PATCH] ifcvt: Improve tests for predicated operations

-msve-vector-bits=128 causes the AArch64 port to list 128-bit Advanced SIMD as the first-choice mode for vectorisation, with SVE being used for things that Advanced SIMD can't handle as easily. However, ifcvt would not then try to use SVE's predicated FP arithmetic, leading to tests like TSVC Cont
