Subject: Mostly finish up constant islands port for Mips for load constants.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=50d3b27f431a213a53a0240849a8ce65dc46c8a5;p=oota-llvm.git

Mostly finish up constant islands port for Mips for load constants.
Still need to finish the branch part. Still lots more review of the code,
clean up and testing.
