Richard Henderson - Feb. 20, 2010, 7:46 p.m.
Delete inline functions from tcg-target.h that don't need to be there,
move the others to tcg-target.c.  Add 'Z', 'I', 'J' constraints for
0, signed 11-bit, and signed 5-bit respectively.  Add 'c' constraint
for RET1 register.  Add GUEST_BASE support similar to ppc64, with the
value stored in a register.  Add missing registers to reg_alloc_order.
Add support for 12-bit branch relocations.  Add functions for synthetic
operations: addi, mtctl, dep, shd, vshd, ori, andi, shifts, rotates,
multiply, millicode calls, branches, setcond.  Split out TLB reads from
qemu_ld and qemu_st; fix argument loading for tlb external calls.
Generate the prologue.
