27bcd47cfa Modify gcc/*.[hc] double_int call sites to use the new interface. 
This change entailed adding a few new methods to double_int.

The change results in a 0.163% time improvement with a 70% confidence.

Tested on x86_64.

b9c8da345c Add -Wvarargs option 
Several warnings related to questionable usage cases of variadic
function related macros (like va_start) could not be controlled by any
warning-related macro.  Fixed thus, by introducing the -Wvarargs
option.

Tested on x86_64-unknown-linux-gnu against trunk.

gcc/c-family/

	* c.opt (Wvarargs):  Define new option.

gcc/
	* builtins.c (fold_builtin_next_arg):  Use OPT_Wvarargs as an
	argument for the various warning_at calls.

34c8879087 Fix va_start related location 
In gcc/testsuite/gcc.dg/pr30457.c, the first warning was not being
emitted because the relevant location was inside the var_start macro
defined in a system header.  It can even point to a token for a
builtin macro there.  This patch unwinds to the first token in real
source code in that case.

Tested on x86_64-unknown-linux-gnu against trunk.

	* builtins.c (fold_builtin_next_arg): Unwinds to the first
	location in real source code.

cedb4a1ad0 Allow libcalls to be installed for legacy __sync optabs. 
This allows a target which implements the __sync interfaces

This is true of all extant libgcc instances.
