338b61e9e9 tcg: Replace REG_P with arg_loc_reg_p
An inline function is safer than a macro, and REG_P
was rather too generic.

39004a71d8 tcg: Reorg function calls
Pre-compute the function call layout for each helper at startup.
Drop TCG_CALL_DUMMY_ARG, as we no longer need to leave gaps
in the op->args[] array.  This allows several places to stop
checking for NULL TCGTemp, to which TCG_CALL_DUMMY_ARG mapped.

For tcg_gen_callN, loop over the arguments once.  Allocate the TCGOp
for the call early but delay emitting it, collecting arguments first.
This allows the argument processing loop to emit code for extensions
and have them sequenced before the call.

For tcg_reg_alloc_call, loop over the arguments in reverse order,
which allows stack slots to be filled first naturally.

aef8540290 tcg: Allocate TCGTemp pairs in host memory order
Allocate the first of a pair at the lower address, and the
second of a pair at the higher address.  This will make it

3e92aa3443 tcg: Store the TCGHelperInfo in the TCGOp for call
This will give us both flags and typemask for use later.

We also fix a dumping bug, wherein calls generated for plugins
fail tcg_find_helper and print (null) instead of either a name
or the raw function pointer.
