Rename the routines to reflect the reality that they are more related to call frame information than to Win64 EH. Although EH is implemented in an intertwined manner by augmenting with an exception handler and an associated parameter, the majority of these routines emit information required to unwind the frames. This also helps identify that these routines are generic for most windows platforms (they apply equally to nearly all architectures except x86) although the encoding of the information is architecture dependent. Unwinding data is emitted via EmitWinCFI* and exception handling information via EmitWinEH*. llvm-svn: 211994
