regcache_raw_read_as_address() with a call to
regcache_cooked_read_unsigned(). The old, ...as_address
function was eventually calling extract_unsigned_integer (via
extract_address) to unpack the registers value. The below is
doing an unsigned extract so that it is functionally
equivalent. The read needs to be cooked as, otherwise, it
will never correctly return the value of a register in the
[NUM_REGS .. NUM_REGS+NUM_PSEUDO_REGS) range. */
