22613af4a6 Add copy and constant propagation.

preparational work before actual constant folding.

8f2e8c07a6 Add TCG optimizations stub 
Added file tcg/optimize.c to hold TCG optimizations. Function tcg_optimize
is called from tcg_gen_code_common. It calls other functions performing
specific optimizations. Stub for constant folding was added.
