David Malcolm ec3fafa9ec analyzer: fix bitfield endianness issues [PR99212,PR101082]
Looks like my patch for PR analyzer/99212 implicitly assumed
little-endian, which the following patch fixes.

Fixes bitfields-1.c on:
- armeb-none-linux-gnueabihf
- cris-elf
- powerpc64-darwin
- s390-linux-gnu

gcc/analyzer/ChangeLog:
	PR analyzer/99212
	PR analyzer/101082
	* engine.cc: Include "target.h".
	(impl_run_checkers): Log BITS_BIG_ENDIAN, BYTES_BIG_ENDIAN, and
	WORDS_BIG_ENDIAN.
	* region-model-manager.cc
	(region_model_manager::maybe_fold_binop): Move support for masking
	via ARG0 & CST into...
	(region_model_manager::maybe_undo_optimize_bit_field_compare):
	...this new function.  Flatten by converting from nested
	conditionals to a series of early return statements to reject
	failures.  Reject if type is not unsigned_char_type_node.
	Handle BYTES_BIG_ENDIAN when determining which bits are bound
	in the binding_map.
	* region-model.h
	(region_model_manager::maybe_undo_optimize_bit_field_compare):
	New decl.
	* store.cc (bit_range::dump): New function.
	* store.h (bit_range::dump): New decl.

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.
