135ffda8b8 Tighten up vfprintf width, precision, and total length overflow handling.
With help from Paul Eggert, Carlos O'Donell, and Roland McGrath.
	* stdio-common/printf-parse.h (read_int): Change return type to
	'int', return -1 on INT_MAX overflow.
	* stdio-common/vfprintf.c (vfprintf): Validate width and precision
	against overflow of INT_MAX.  Set errno to EOVERFLOW when 'done'
	overflows INT_MAX.  Check for overflow of in-format-string precision
	values properly.  Use EOVERFLOW rather than ERANGE throughout.  Use
	SIZE_MAX not INT_MAX for integer overflow test.
	* stdio-common/printf-parsemb.c: If read_int signals an overflow,
	skip the construct in the format string but do not record anything.
	* stdio-common/bug22.c: Adjust to test both width/prevision
	INT_MAX overflow as well as total length INT_MAX overflow.  Check
	explicitly for proper errno values.

b48a267b8f Preserve SSE registers in runtime relocations on x86-64.
SSE registers are used for passing parameters and must be preserved
in runtime relocations.  This is inside ld.so enforced through the
tests in tst-xmmymm.sh.  But the malloc routines used after startup
come from libc.so and can be arbitrarily complex.  It's overkill
to save the SSE registers all the time because of that.  These calls
are rare.  Instead we save them on demand.  The new infrastructure
put in place in this patch makes this possible and efficient.
