Make tcg_constant_folding do copy and constant propagation. It is a
preparational work before actual constant folding.

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.
