The platform independent ISD::INSERT_VECTOR_ELT take a element index,
but vins* instructions take a byte index. Update 32bit td patterns for
vector insert to handle the element index accordingly.
Since vector insert for non constant index are supported in
ISA3.1, there is no need to use platform specific ISD node,
PPCISD::VECINSERT. Update td pattern to directly use
ISD::INSERT_VECTOR_ELT instead.

This patch exploits the prefixed load and store instructions utilizing the
refactored load/store implementation introduced in D93370.
Prefixed load and store instructions are emitted whenever we are loading or
storing a value with an offset that fits into a 34-bit signed immediate.
Patterns for the prefixed load and stores are added in this patch, as well as
the implementation that detects when we are loading and storing a value with an
offset that fits in 34-bits.

The code gen for f32 to i32 bitcast is not currently the most efficient;
this patch removes some unneccessary instructions gerneated.
