cmd/compile: add indexed form for several 386 instructions
This CL implements indexed memory operands for the following instructions.
(ADD|SUB|MUL|AND|OR|XOR)Lload -> (ADD|SUB|MUL|AND|OR|XOR)Lloadidx4
(ADD|SUB|AND|OR|XOR)Lmodify -> (ADD|SUB|AND|OR|XOR)Lmodifyidx4
(ADD|AND|OR|XOR)Lconstmodify -> (ADD|AND|OR|XOR)Lconstmodifyidx4
1. The total size of pkg/linux_386/ decreases about 2.5KB, excluding
cmd/compile/ .
2. There is little regression in the go1 benchmark test, excluding noise.
