Use the same code as system mode, so that we generate the same
exception + syndrome for the unaligned access.
For the moment, if MTE is enabled so that this path is reachable,
this would generate a SIGSEGV in the user-only cpu_loop. Decoding
the syndrome to produce the proper SIGBUS will be done later.

The IL bit is set for 32-bit instructions, thus passing false
with the is_16bit parameter to syn_data_abort_with_iss() makes
a syn mask that always has the IL bit set.
Pass is_16bit as true to make the initial syn mask have IL=0,
so that the final IL value comes from or'ing template_syn.

These routines are TCG specific.
The arm_deliver_fault() function is only used within the new
helper. Make it static.
