    Normally the backend will do deadcode elimination and this is

    do not.
    
    This CL adds a simple deadcode elimination, run before the escape

Darwin produces aligned zerofill directives for the objects represented.
We can scan for these using "lp64" and "ilp32" to catch operation on both
X86 and PowerPC ports (the test is for the alignment which is the trailing
value in the zerofill directive, as a power of two).

When libgcc is built on Darwin, it is usually built for the earliest potential
target (Darwin8, 10.4).  Build for that revision default to assuming that the
processor might be G3 (without vector ops) and there is an outlined function
used for save/restore that checks whether the processor is G3 or G4+ at run-
time.  However, the unwinder itself needs to be built with the assumption of
vector usage so that the relevant outlined functions are called.

This can greatly reduce the amount of preprocessed code that is included
by other headers, because <stdexcept> depends on <string> which is huge.

	* include/std/optional: Include <exception> and
	<bits/exception_defines.h> instead of <stdexcept>.
	* testsuite/20_util/function_objects/searchers.cc: Include <cctype>
	for std::isalnum.
