Jack Carter 2f68b311a1 Initial assembler implementation of Mips load address macro 
This patch provides initial implementation of load address 
macro instruction for Mips. We have implemented two kinds 
of expansions with their variations depending on the size 
of immediate operand:

 1) load address with immediate value directly:
    * la d,j => addiu d,$zero,j   (for -32768 <= j <= 65535)
    * la d,j => lui d,hi16(j)
                ori d,d,lo16(j)   (for any other 32 bit value of j)

 2) load load address with register offset value
    * la d,j(s) => addiu d,s,j     (for -32768 <= j <= 65535)
    * la d,j(s) => lui d,hi16(j)   (for any other 32 bit value of j)
                   ori d,d,lo16(j)
                   addu d,d,s

This patch does not cover the case when the address is loaded 
from the value of the label or function.
