This patch moves the below instructions to decodetree specification :
f{add, sub, mul, div, re, rsqrte, madd, msub, nmadd, nmsub}[s][.] : A-form
ft{div, sqrt} : X-form
With this patch, all the floating-point arithmetic instructions have been
moved to decodetree.
The changes were verified by validating that the tcg ops generated by those
instructions remain the same, which were captured with the '-d in_asm,op' flag.
