[PR67753] adjust for padding when bypassing memory in assign_parm_setup_block
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.

fix PR68453: recursively add phi nodes to merge points
The patch adds close phi nodes to every outer loop exit, and to every loop
guard. For loop guards it computes an initial value that determines where we
stop inserting phi nodes. When the initial value is a constant, the initial
value is considered to be defined in the entry of the code gen region.
