Build the infrastructure to create overrides for HVX instructions.
We create a new empty file (gen_tcg_hvx.h) that will be populated
in subsequent patches.

Change additional tcg_const_tl to tcg_constant_tl
Note that gen_pred_cancal had slot_mask initialized with tcg_const_tl.
However, it is not constant throughout, so we initialize it with
tcg_temp_new and replace the first use with the constant value.

Multiple writes to the same preg are and'ed together. Rather than
generating a runtime check, we can determine at TCG generation time
if the predicate has previously been written in the packet.
Test added to tests/tcg/hexagon/misc.c

Python scripts generate the following files
helper_protos_generated.h.inc
For each instruction we create DEF_HELPER function prototype
helper_funcs_generated.c.inc
For each instruction we create the helper function definition
tcg_funcs_generated.c.inc
For each instruction we create TCG code to generate call to helper
tcg_func_table_generated.c.inc
Table of function pointers indexed by opcode
shortcode_generated.h.inc
Generate a table of instruction "shortcode" semantics
opcodes_def_generated.h.inc
Gives a list of all the opcodes
op_attribs_generated.h.inc
Lists all the attributes associated with each instruction
op_regs_generated.h.inc
Lists the register and immediate operands for each instruction
printinsn_generated.h.inc
Data for printing (disassembling) each instruction (format
string + operands)
