Have you considered joining this and the above into a combined "#if 0"/"#endif"
region, instead of two adjacent regions?  This might make it easier in the
future to identify assembler routines that haven't been brought over but maybe
should.  Your call.

Sounds reasonable, since it make the file easier to read. Fixed all such cases
in the file (and did the same to assembler_arm.cc).
