  SLP cannot vectorize frem calls in AArch64.

It needs updated costs when there are available vector library functions
given the VF and type.

  [AArch64] SLP can vectorize frem

When vector library calls are available for frem, given its type and
vector length, the SLP vectorizer uses updated costs that amount to a
call, matching LoopVectorizer's functionality.

This allows 'superword-level' vectorization, which can be converted to
a vector lib call by later passes.

Add tests that vectorize code that contains 2x double and 4x float frem
instructions.

  [LV][SLP] Vectorizers now use getFRemInstrCost for frem costs

SLP vectorization for frem now happens when vector library calls are
available, given its type and vector length. This is due to using the
updated cost that amounts to a call.

Add tests that do SLP vectorization for code that contains 2x double and
4x float frem instructions.

LoopVectorizer now also uses getFRemInstrCost.
