6eea04347e tcg/tci: Implement goto_ptr
This operation is critical to staying within the interpretation
loop longer, which avoids the overhead of setup and teardown for
many TBs.

The check in tcg_prologue_init is disabled because TCI does
want to use NULL to indicate exit, as opposed to branching to
a real epilogue.

79dd3a4f59 tcg/tci: Clean up deposit operations
Use the correct set of asserts during code generation.
We do not require the first input to overlap the output;
the existing interpreter already supported that.

Split out tci_args_rrrbb in the translator.
Use the deposit32/64 functions rather than inline expansion.

2f74f45e32 tcg/tci: Remove TCG_CONST
Restrict all operands to registers.  All constants will be forced
into registers by the middle-end.  Removing the difference in how
immediate integers were encoded will allow more code to be shared
between 32-bit and 64-bit operations.

63b29fda4e tcg/tci: Split out constraint sets to tcg-target-con-set.h
This requires finishing the conversion to tcg_target_op_def.
