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.
Depends on D95116.
