5410e4347b tcg/tci: Inline tci_write_reg64 into 64-bit callers
Note that we had two functions of the same name: a 32-bit version
which took two register numbers and a 64-bit version which was a
no-op wrapper for tcg_write_reg.  After this, we are left with
only the 32-bit version.

85bbbf7088 tcg/tci: Inline tci_write_reg32 into all callers
For a 64-bit TCI, the upper bits of a 32-bit operation are
undefined (much like a native ppc64 32-bit operation).  It
simplifies everything if we don't force-extend the result.

13e71f08bf tcg/tci: Make tci_tb_ptr thread-local
Each thread must have its own pc, even under TCI.

Remove the GETPC ifdef, because GETPC is always available for
helpers, and thus is always required.  Move the assignment
under INDEX_op_call, because the value is only visible when
we make a call to a helper function.

2dfa2f1871 tcg/aarch64: Do not convert TCGArg to temps that are not temps
Fixes INDEX_op_rotli_vec for aarch64 host, where the 3rd
argument is an integer, not a temporary, which now tickles
an assert added in e89b28a635.

Previously, the value computed into v2 would be garbage for
rotli_vec, but as the value was unused it caused no harm.

8e43c5a1f2 tcg/s390: Fix compare instruction from extended-immediate facility
The code is currently comparing c2 to the type promotion of
uint32_t and int32_t. That is, the conversion rules are as:

  (common_type) c2 == (common_type) (uint32_t)
                        (is_unsigned
                        ? (uint32_t)c2
                        : (uint32_t)(int32_t)c2)

In the signed case we lose the desired sign extensions because
of the argument promotion rules of the ternary operator.

Solve the problem by doing the round-trip parsing through the
intermediate type and back to the desired common type (all at
one expression).
