separate functions.

tcg-i386: Tidy immediate arithmetic operations.

Define OPC_ARITH_EvI[bz]; use throughout. Use tcg_out_ext8u
directly in setcond. Use tgen_arithi in qemu_ld/st.

tcg-i386: Tidy non-immediate arithmetic operations.

Add more OPC values, and tgen_arithr. Use the later throughout.

Note that normal reg/reg arithmetic now uses the Gv,Ev opcode form
instead of the Ev,Gv opcode form used previously. Both forms
disassemble properly, and so there's no visible change when diffing...

tcg-i386: Tidy push/pop.

Move tcg_out_push/pop up in the file so that they can be used
by qemu_ld/st. Define a tcg_out_pushi to be used as well.

tcg-i386: Tidy calls.

Define OPC_CALL_Jz, generated by tcg_out_calli; use the later
throughout. Unify the calls within qemu_st; adjust the stack
with a single pop if applicable.

Define and use EXT_CALLN_Ev for indirect calls.

tcg-i386: Tidy unary arithmetic.

Define OPC_GRP3 and EXT3_FOO to match. Use them instead of
bare constants.

Define OPC_GRP5 and rename the existing EXT_BAR to EXT5_BAR to
make it clear which extension should be used with which opcode.
