SelectionDAGISel.cpp updated: 1.125 -> 1.126

Log message:

For PR411: http://llvm.cs.uiuc.edu/PR411 :
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.
