Changes since v2:
* Fixes to aarch64 guest. Some tcg_debug_asserts were triggering.
* Silly typo fixed in tcg/mips
* tcg/README updated.
Changes since v1:
* Added tcg_gen_deposit_z_*. Depositing into zero turns out to be
quite common among targets. Providing that as a primitive expander
allows us to easily generate optimal-ish code for hosts with and
without a real deposit operation.
* Cleanups in tcg/s390 akin to those I already did for tcg/arm.
* Add support in tcg/s390 for deposit into zero.
* More special cases in the expanders for better code generation,
especially on an x86 host *without* the extract primitives.
* Silly think-o on aarch64 host.
