Large code model on PPC64 requires creating and referencing TOC entries when using the addis/ld form of addressing. This was not being done in all cases. The changes in this patch to PPCAsmPrinter::EmitInstruction() fix this. Two test cases are also modified to reflect this requirement. Fast-isel was not creating correct code for loading floating-point constants using large code model. This also requires the addis/ld form of addressing. Previously we were using the addis/lfd shortcut which is only applicable to medium code model. One test case is modified to reflect this requirement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190882 91177308-0d34-0410-b5e6-96231b3b80d8
