Use a more efficient lowering of uint64_t --> float that can take advantage of hardware signed integer conversion without
having to do a double cast (uint64_t --> double --> float).  This is based on the algorithm from compiler_rt's __floatundisf
for X86-64.

Make sure it restores local variable N1, which corresponds to the condition operand if it fails to match.

This apparently breaks TCE but since that backend isn't in the tree I don't have a test for it.

1) Changed ValidateDwarfFileNumber() to isValidDwarfFileNumber() to be better
   named.  Since it is just a predicate and isn't actually changing any state.

2) Added a missing return in the comments for setCurrentDwarfLoc() in 
   include/llvm/MC/MCContext.h for fix formatting.

3) Changed clearDwarfLocSeen() to ClearDwarfLocSeen() since it does change
   state.

4) Simplified the last test in isValidDwarfFileNumber() to just a one line
   boolean test of MCDwarfFiles[FileNumber] != 0 for the final return statement.
