Storing a register in memory as a full word and then accessing the
same memory address under a smaller-than-word mode amounts to
right-shifting of the register word on big endian machines.  So, if
BLOCK_REG_PADDING chooses upward padding for BYTES_BIG_ENDIAN, and
we're copying from the entry_parm REG directly to a pseudo, bypassing
any stack slot, perform the shifting explicitly.

This fixes the miscompile of function_return_val_10 in
gcc.target/aarch64/aapcs64/func-ret-4.c for target aarch64_be-elf
introduced in the first patch for 67753.

	* function.c (assign_parm_setup_block): Right-shift
	upward-padded big-endian args when bypassing the stack slot.

Move the `-mcompact-branches=' option out of the middle of a block of
floating-point options.  The option is not related to FP in any way.
Place it immediately below other branch instruction selection options.

	* doc/invoke.texi (Option Summary) <MIPS Options>: Reorder
	`-mcompact-branches='.
	(MIPS Options): Likewise.
