Quick Compiler: Shoot the Camel

Another step towards moving the Quick Compiler from the old
Dalvik coding style to Art's coding style.  In this CL, Camel-case
locals, struct variables and arguments are converted to lower-case
with underscore names.  Most of the name changes were formulistic,
but I also took this opportunity to change the old "printMe" into
the more traditional "verbose", and shorten cUnit to cu.

No logic changes.
