Now that the implementation is entirely within the generated
decode function, eliminate the wrapper.

When QEMU is compiled with -O0, these functions are inlined
which will cause a wrong restart address generated for the TB.

We will be fixing do_cond vs signed overflow, which requires
that do_log_cond not rely on do_cond.

It looks like the operands where exchanged. HP bootrom tests the
following sequence:

0x00000000f0004064:  ldil L%-66666800,r7
0x00000000f0004068:  addi 19f,r7,r7
0x00000000f000406c:  addi -1,r0,rp
0x00000000f0004070:  addi f,r0,r4
0x00000000f0004074:  addi 1,r4,r5
0x00000000f0004078:  dcor rp,r6
0x00000000f000407c:  cmpb,<>,n r6,r7,0xf000411

This returned 0x66666661 instead of the expected 0x9999999f in QEMU.

HP-UX 10.20 uses busmaster writes to the CPU EIR to signal
interrupts from the SCSI constroller. (Similar to what is known
as MSI on x86)
