AMDGPU/SI: Extend promoting alloca to vector to arrays of up to 16 elements Summary: This patch extends the promotion of alloca to vector to the arrays of up to 16 elements. Also we introduce an option, -disable-promote-alloca-to-vector, to switch promotion to vector off, if needed. Reviewers: arsenm Differential Revision: https://reviews.llvm.org/D33559 llvm-svn: 325372
