small patch for a29k

[Andrew Macleod <amacleod at cygnus dot com>]

I'm checking in the following changes which are required to get the a29k 
target to compile.  oballoc needs to be replaced with xmalloc and free, and 
'shift_constant_operand' is static to a29k.c so having it in the 
PREDICATE_CODES causes a function proototype to be declared which conflicts
with the actual function.

Approved by rth.


Andrew

	* config/a29k/a29k.c (print_operand): Free a29k_last_prologue_insn
	after its emitted.
	(output_prologue): Use xmalloc not oballoc.
	(output_epilog): Free a29k_first_epilogue_insn when finished.
	* confif/a29k/a29k.h (PREDICATE_CODES): Remove shift_constant_operand.
