Options

lib1funcs.asm: Rename abi_entry/abi_return macros to leaf_entry/leaf_return. 

	* config/xtensa/lib1funcs.asm: Rename abi_entry/abi_return macros
	to leaf_entry/leaf_return.  Change leaf_entry to add 16 bytes to
	the frame size.  Update to use the new macros.
	* config/xtensa/ieee754-sf.S: Use new leaf_entry/leaf_return macros.
	* config/xtensa/ieee754-df.S: Likewise.
