[AMDGPU] Fix incorrect register pressure calculation
Earlier fix D32572 introduced a bug where live-ins were calculated
for basic block instead of scheduling region. This change fixes it.

I get an assertion with Unreal Tournament alpha.
The game loads and some tutorials work, but since above the death match
tutorial bails. It was never perfect (some scenery sometimes rendered black) -
but it was mostly OK - it is an alpha game.
UE4-Linux-Shipping: /mnt/sdb1/Gits/llvm/lib/CodeGen/LiveRangeEdit.cpp:258: void
llvm::LiveRangeEdit::eliminateDeadDef(llvm::MachineInstr*,
llvm::LiveRangeEdit::ToShrinkSet&, llvm::AliasAnalysis*): Assertion
`MI->allDefsAreDead() && "Def isn't really dead"' failed.
Signal 6 caught.
Attached output assert with R600_DEBUG=vs,ps,fs bz2</pre>
