tccgen.c: Optimise 0<<x, 0>>x, -1>>x, x&0, x*0, x|-1, x%1.
...
More precisely, treat (0 << x) and so on as constant expressions, but
not if const_wanted as we do not want to allow "case (x*0):", ...
Do not optimise (0 / x) and (0 % x) here as x might be zero, though
for an architecture that does not generate an exception for division
by zero the back end might choose to optimise those.

Add __builtin_return_address.
...
Implementation is mostly shared with __builtin_frame_address.
It seems to work on arm64, i386 and x86_64. It may need to be
adapted for other targets.

Fix handling of case_reg in switch statement.
...
The back end functions gen_op(comparison) and gtst() might allocate
registers so case_reg should be left on the value stack while they
are called and set again afterwards.
