When a large number of bytes are pushed in a function call sequence on
the H8, the call patterns to fail to match because they expect the
operand to be a valid HImode operand -- even when pointers are SImode.

The fact that the operand is expected to be in HImode is a bit of a
historical wart that we got away with for a long time.  This patch
changes the operand to vary between HImode and SImode based on Pmode
using the existing mode iterator.

This fixes a few dozen failures in the testsuite.  None are particularly
important and I suspect all would likely fail at runtime anyway.  But
with the RCA done on the ICE it would have been silly to not fix it
given how easy it was.

Installing on the trunk.

            * config/h8300/h8300.md (call, call_value): Drop mode from
            operand containing number of bytes pushed.
            (call_insn, call_value_insn): Use mode iterator for number
            of bytes pushed operand.  Make pattern name vary appropriately.
