Tamar Christina 329130cc40 Validate and set default parameters for stack-clash.
This patch defines the default parameters and validation for the aarch64
stack clash probing interval and guard sizes.  It cleans up the previous
implementation and insures that at no point the invalidate arguments are
present in the pipeline for AArch64.  Currently they are only corrected once
cc1 initalizes the back-end.

The default for AArch64 is 64 KB for both of these and we only support 4 KB and 64 KB
probes.  We also enforce that any value you set here for the parameters must be
in sync.

If an invalid value is specified an error will be generated and compilation aborted.

	* common/config/aarch64/aarch64-common.c (TARGET_OPTION_DEFAULT_PARAM,
	aarch64_option_default_param):	New.
	(params.h): Include.
	(TARGET_OPTION_VALIDATE_PARAM, aarch64_option_validate_param): New.
	* config/aarch64/aarch64.c (aarch64_override_options_internal): Simplify
	stack-clash protection validation code.

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
