David Malcolm da7cf663b7 analyzer: testsuite fixes for alloca, getpass, and setjmp (PR 93316)
PR analyzer/93316 reports various testsuite failures where I
accidentally relied on properties of x86_64-pc-linux-gnu.

The following patch fixes them on sparc-sun-solaris2.11 (gcc211 in the
GCC compile farm), and, I hope, the other configurations showing
failures.

There may still be other failures for pattern-test-2.c, which I'm
tracking separately as PR analyzer/93291.

gcc/analyzer/ChangeLog:
	PR analyzer/93316
	* analyzer.cc (is_setjmp_call_p): Check for "setjmp" as well as
	"_setjmp".

gcc/testsuite/ChangeLog:
	PR analyzer/93316
	* gcc.dg/analyzer/data-model-1.c: Include <alloca.h>.
	* gcc.dg/analyzer/malloc-1.c: Likewise.
	* gcc.dg/analyzer/malloc-callbacks.c (get_alloca): Return
	__builtin_alloca rather than alloca.
	* gcc.dg/analyzer/malloc-paths-8.c: Include <alloca.h>.
	* gcc.dg/analyzer/sensitive-1.c: Define __EXTENSIONS__ before
	including unistd.h.
	* gcc.dg/analyzer/setjmp-2.c: Replace include of <setjmp.h>
	with "test-setjmp.h" and usage of setjmp with new SETJMP macro.
	* gcc.dg/analyzer/setjmp-3.c: Likewise.
	* gcc.dg/analyzer/setjmp-4.c: Likewise.
	* gcc.dg/analyzer/setjmp-5.c: Likewise.

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.
