This patch sets the branch cost to the same most optimal setting for all Cortex
cores, reducing codesize and improving performance due to using more CSEL
instructions.  Set the autoprefetcher model in Cortex-A72 to weak like the
others.  Enable AES fusion in Cortex-A35.  As a result generated code is now
more similar as well as more optimal across Cortex cores.

    gcc/
	* config/aarch64/aarch64.c (cortexa35_tunings):
	Enable AES fusion.  Use cortexa57_branch_cost.
	(cortexa53_tunings): Use cortexa57_branch_cost.
	(cortexa72_tunings): Use cortexa57_branch_cost.
	Use AUTOPREFETCHER_WEAK.

From-SVN: r237823

This patch fixes a bug in the bswap pass.  In big-endian BIT_FIELD_REF uses
big-endian bit numbering so we need to adjust the bit position.
The existing version could potentially generate incorrect code however GCC
doesn't emit a BIT_FIELD_REF to access the low byte in a register, so the
symbolic number never matches in big-endian.

    gcc/
	* tree-ssa-math-opts.c (find_bswap_or_nop_1): Adjust bitnumbering
	for big-endian BIT_FIELD_REF.
