[PATCH] D26036: [mips] Always run the MipsOptimizePICCall pass.

[Vasileios Kalintiris via llvm-commits]

vkalintiris created this revision.
vkalintiris added a reviewer: sdardis.
vkalintiris added a subscriber: llvm-commits.

Remove this pass from addMachineSSAOptimization() and register it unconditionally in through addPreRegAlloc(). This pass is required for generating correct PIC calls.
