Add testing files and enable streaming mode flag for:
bit-counting.ll
bitselect.ll
insert-vector-elt.ll
subvector.ll
vector-shuffle.ll
Add needed changes to force generateing code compatible to streaming mode:
1- enable custom lowering for CTLZ and CTPOP, (needed for bit-counting.ll test).
2- enable custom lowering for insert_vector_elt, (needed for insert-vector-elt.ll test).
3- enable custom lowering for vector SETCC, (needed for subvector.ll test).
4- disable combining or into BSL, (needed for bit-select.ll test).
5- use SVE OR instruction instead of NEON OR, during copying phyReg -AArch64InstrInfo::copyPhysReg-, (needed for vector-shuffle).
