Manoj Gupta	31cc06a8d8	[LoopVectorizer] Add more testcases for PR33804. Summary: Add test cases when float <-> pointer types conversion is triggered in presence of load instructions.

Manoj Gupta	5d292d77f5	[LoopVectorizer] Use two step casting for float to pointer types. Summary: LoopVectorizer is creating casts between vec<ptr> and vec<float> types on ARM when compiling OpenCV. Since, tIs is illegal to directly cast a floating point type to a pointer type even if the types have same size causing a crash. Fix the crash using a two-step casting by bitcasting to integer and integer to pointer/float. Fixes PR33804.
