Hexagon (target/hexagon) Remove redundant/unused macros

Commit Message

Taylor Simpson April 5, 2023, 6:30 p.m. UTC

Remove the following macros (remnants of the old generator design)
    READ_REG
    READ_PREG
    WRITE_RREG
    WRITE_PREG
Modify macros that rely on the above

The following are unused
    READ_IREG
    fGET_FIELD
    fSET_FIELD
    fREAD_P3
    fREAD_NPC
    fWRITE_LC0
    fWRITE_LC1
