[mips] MIPS-IV is broadly the same as MIPS64 so duplicate all -mcpu=mips64 tests with -mcpu=mips4 as a starting point Summary: Two exceptions to this: test/CodeGen/Mips/octeon.ll test/CodeGen/Mips/octeon_popcnt.ll these test extensions to MIPS64 One test is altered for MIPS-IV: test/CodeGen/Mips/mips64countleading.ll Tests dclo/dclz which were added in MIPS64. The MIPS-IV version tests that dclo/dclz are not emitted. Four tests fail and are not in this patch: test/CodeGen/Mips/abicalls.ll test/CodeGen/Mips/fcopysign-f32-f64.ll test/CodeGen/Mips/fcopysign.ll test/CodeGen/Mips/stack-alignment.ll Depends on D3343 Reviewers: matheusalmeida, vmedic Reviewed By: vmedic Differential Revision: http://reviews.llvm.org/D3344 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206185 91177308-0d34-0410-b5e6-96231b3b80d8
