LAA cannot vectorize lib calls like modf/modff
Functions like modf/modff are math lib calls that set memory write-only
attribute. Given that a target has vectorized mappings, LAA should allow
vectorization.

[LV][LAA] Vectorize math lib calls with mem write-only attribute
Teach LAA to consider safe specific math lib calls which are known to
have set the memory write-only attribute. Those attributes are set to
calls by inferNonMandatoryLibFuncAttrs, in BuildLibCalls.cpp, and the
current ones are modf/modff and frexp/frexpf.
This happens only when the calls are found through TLI to have
vectorized counterparts.
