Hi, this is the parent revision for the https://reviews.llvm.org/D62401.
Briefly AMDGPU backend needs live-in/live-out virtual register sets to calculate register pressure for the beginning/ending of every basic block on scheduling. For the large number of BBs this takes minutes. This patch makes it times faster.
