[Bug target/16563] The compiler doesnt the necessary push/restore of r18/r19

I can confirm the bug, as well as the regression against GCC 3.3.x.

In GCC 3.3.x, parameter `d' (in Martin's test case) has been internally
copied over to r14 through r17, and that value was used then.  In GCC 3.4.x,
`d' is no longer saved, so wrong values will be passed on once a called
function has modified r18 and/or r19 (which it is free to do according to the
ABI specification).
