tci: Support targets with CONFIG_TCG_PASS_AREG0 (fix broken build)

Builds with --enable-tcg-interpreter failed because more and more
targets (currently alpha and sparc) replaced the global env in AREG0
by function parameters.

Convert the TCG interpreter to use the new helper functions and add
defines for those targets which still use AREG0.
