Last change for mips16 prolog/epilog cleanup and optimization. Some tiny cosmetic code changes to follow. Because of the wide ranging nature of the patch a full 24 test cycle was needed to check against regression. This was the smallest patch I could make to progress from the earlier ones in the series. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197350 91177308-0d34-0410-b5e6-96231b3b80d8

; RUN: llc -mtriple=mipsel-linux-gnu -march=mipsel -mcpu=mips16 -relocation-model=pic < %s | FileCheck %s -check-prefix=PIC
Next step in Mips16 prologue/epilogue cleanup. Save S2(reg 18) only when we are calling floating point stubs that have a return value of float or complex. Some more work to make this better but this is the first step. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196921 91177308-0d34-0410-b5e6-96231b3b80d8
