Add NVPTXPeephole pass to reduce unnecessary address cast
Summary:
This patch first change the register that holds local address for stack
frame to %SPL. Then the new NVPTXPeephole pass will try to scan the
following pattern
%vreg0<def> = LEA_ADDRi64 <fi#0>, 4
%vreg1<def> = cvta_to_local %vreg0
and transform it into
%vreg1<def> = LEA_ADDRi64 %VRFrameLocal, 4
