* calls.c (compute_argument_block_size): Add argument tree fndecl.
(OUTGOING_REG_PARM_STACK_SPACE): Add function type argument.
(emit_library_call_value_1): Add new variable fndecl initialized by
NULL_TREE. It should be the decl type of orgfun, but this information
seems not to be available here, so it uses the default calling abi.
* config/arm/arm.c (arm_return_in_memory): Add fntype argumen.
* config/arm/arm.h (RETURN_IN_MEMORY): Replace RETURN_IN_MEMORY
by TARGET_RETURN_IN_MEMORY.
* config/i386/i386-interix.h: Likewise.
* config/i386/i386.h: Likewise.

* config/arm/arm-protos.h (arm_return_in_memory): Add fntype
argument.
* config/i386/i386-protos.h (ix86_return_in_memory): Add fntype
argument.
(ix86_sol10_return_in_memory): Likewise.
(ix86_i386elf_return_in_memory): New.
(ix86_i386interix_return_in_memory): New.
* config/mt/mt-protos.h (mt_return_in_memory): New.
* config/mt/mt.c: Likewise.
* config/mt/mt.h (OUTGOING_REG_PARM_STACK_SPACE): Add FNTYPE argument.
(RETURN_IN_MEMORY): Replace by TARGET_RETURN_IN_MEMORY.
* config/bfin/bfin.h: Likewise.
* config/bfin/bfin-protos.h (bfin_return_in_memory): Add fntype
argument.
* config/bfin/bfin.c: Likewise.
* config/pa/pa.h (OUTGOING_REG_PARM_STACK_SPACE): Add FNTYPE argument.
* config/alpha/unicosmk.h: Likewise.

* defaults.h: Likewise.
* doc/tm.texi (OUTGOING_REG_PARM_STACK_SPACE): Adjust documentation.
* expr.c (emit_block_move): Adjust use of OUTGOING_REG_PARM_STACK_SPACE.
* function.c (STACK_DYNAMIC_OFFSET): Adjust use of
OUTGOING_REG_PARM_STACK_SPACE.
* targhooks.c (default_return_in_memory): Remove RETURN_IN_MEMORY.
