Hexagon: fix HVX store new
At 09a7e7db0f (Hexagon (target/hexagon) Remove uses of
op_regs_generated.h.inc, 2024-03-06), we've changed the logic of
check_new_value() to use the new pre-calculated
packet->insn[...].dest_idx instead of calculating the index on the fly
using opcode_reginfo[...]. The dest_idx index is calculated roughly like
the following:
for reg in iset[tag]["syntax"]:
if reg.is_written():
dest_idx = regno
break
Thus, we take the first register that is writtable. Before that,
however, we also used to follow an alphabetical order on the register
type: 'd', 'e', 'x', and 'y'. No longer following that makes us select
the wrong register index and the HVX store new instruction does not
update the memory like expected.

Hexagon: add PC alignment check and exception
The Hexagon Programmer's Reference Manual says that the exception 0x1e
should be raised upon an unaligned program counter. Let's implement that
and also add some tests.

target/hexagon: idef-parser remove unused defines
Before switching to GArray/g_string_printf we used fixed size arrays for
output buffers and instructions arguments among other things.
Macros defining the sizes of these buffers were left behind, remove
them.

target/hexagon: idef-parser fix leak of init_list
gen_inst_init_args() is called for instructions using a predicate as an
rvalue. Upon first call, the list of arguments which might need
initialization init_list is freed to indicate that they have been
processed. For instructions without an rvalue predicate,
gen_inst_init_args() isn't called and init_list will never be freed.
Free init_list from free_instruction() if it hasn't already been freed.
A comment in free_instruction is also updated.

target/hexagon: idef-parser simplify predicate init
Only predicate instruction arguments need to be initialized by
idef-parser. This commit removes registers from the init_list and
simplifies gen_inst_init_args() slightly.
