Strict Aliasing Fix
Dalvik: Better compatibility with different compilers

This fixes building with clang, and possibly future versions of gcc:
- Don't error out on unused functions generated by gen-mterp.py
  even when we're using -Werror
- Eliminate some dead code (Word/kWordSize definition) clang warns about
- Add a return statement to a switch path causing a possible code path
  with uninitialized variables (if the compiler doesn't know what
  dvmAbort() is)
- Initialize a variable

Add -Wno-unused-but-set-variable to the Dalvik project.

This is to meet long term goal that we don't suppress any warnings in
the global makefile.

dalvik/libdex: Don't reduce optimization level to -O2

Don't reduce optimization level to -O2: It's sufficient to disable
function inlining
