The assembler was able to assemble and then dump back to .s, but
was failing to parse certain directives necessary for valid .o
output:

- .type directives are now recognized to distinguish function symbols and others.
- .size is now parsed to provide function size.

Also makes a small change in StringSwitch.h for some missing
functionality (being able to detect no match).
