Richard Henderson 72258b05fd tcg/mips: Remove ALIAS_PADD, ALIAS_PADDI 
These aliases existed to simplify code for O32 and N32.
Now that the 64-bit abi is the only one supported, we
can use the DADD* instructions directly.

Philippe Mathieu-DaudéandRichard Henderson f032bff1ae tcg/mips: Remove support for 32-bit hosts 
32-bit host support is deprecated since commit 6d701c9bac
("meson: Deprecate 32-bit host support"), released as v10.0.
The next release being v10.2, we can remove the TCG backend
for 32-bit MIPS hosts.

Merge into INDEX_op_{ld,st,ld2,st2}, where "2" indicates that two
inputs or outputs are required. This simplifies the processing of
i64/i128 depending on host word size.

Drop the cast from TCGv_i64 to TCGv_i32 in tcg_gen_extrl_i64_i32
an emit extrl_i64_i32 unconditionally.  Move that special case
to tcg_gen_code when we find out if the output is live or dead.
In this way even hosts that canonicalize truncations can make
use of a store directly from the 64-bit host register.
