…133242)" This reverts commit 130080fab11cde5efcb338b77f5c3b31097df6e6 because it causes issues in testcases similar to coalescer_remat.ll [1], i.e. when we use a VGPR tuple but only write to its lower parts. The high VGPRs would then not be included in the vgpr_count, and accessing them would be an out of bounds violation.
