[NFC] Add scalable vectorisation tests for int/FP <> int/FP conversions
We can already vectorize loops that involve int<>int, fp<>fp, int<>fp and fp<>int conversions, however we didn't previously have any tests for them. This patch adds some tests for each conversion type. Differential Revision: https://reviews.llvm.org/D99951
