tcg-hppa: Finish the port. 

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 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, branches, setcond.  Split out TLB reads
from qemu_ld and qemu_st; fix argument loading for tlb external calls.
Generate the prologue.
