target/arm: Permit T32 LDM with single register

For the Thumb T32 encoding of LDM, if only a single register is
specified in the register list this instruction is UNPREDICTABLE,
with the following choices:
* instruction UNDEFs
* instruction is a NOP
* instruction loads a single register
* instruction loads an unspecified set of registers

Currently we choose to UNDEF (a behaviour chosen in commit
4b222545dbf30 in 2019; previously we treated it as "load the
specified single register").

Unfortunately there is real world code out there (which shipped in at
least Android 11, 12 and 13) which incorrectly uses this
UNPREDICTABLE insn on the assumption that it does a single register
load, which is (presumably) what it happens to do on real hardware,
and is also what it does on the equivalent A32 encoding.

Revert to the pre-4b222545dbf30 behaviour of not UNDEFing
for this T32 encoding.

target/arm: Avoid writing to constant TCGv in trans_CSEL()

In commit 0b188ea05acb5 we changed the implementation of
trans_CSEL() to use tcg_constant_i32(). However, this change
was incorrect, because the implementation of the function
sets up the TCGv_i32 rn and rm to be either zero or else
a TCG temp created in load_reg(), and these TCG temps are
then in both cases written to by the emitted TCG ops.
The result is that we hit a TCG assertion:

qemu-system-arm: ../../tcg/tcg.c:4455: tcg_reg_alloc_mov: Assertion `!temp_readonly(ots)' failed.

(or on a non-debug build, just produce a garbage result)

Adjust the code so that rn and rm are always writeable
temporaries whether the instruction is using the special
case "0" or a normal register as input.
