This patch is an incremental step towards supporting a flat symbol table. It de-overloads the intrinsic functions by providing type-specific intrinsics and arranging for automatically upgrading from the old overloaded name to the new non-overloaded name. Specifically: llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64 llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64 llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64 llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64 llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64 New code should not use the overloaded intrinsic names. Warnings will be emitted if they are used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25366 91177308-0d34-0410-b5e6-96231b3b80d8
