Pointers to functions don't work yet, and pointers to overloaded functions even less. Also, far too much illegal code is accepted.

 - Now only 27/500 failures on ABITest single argument tests; from
   350/500. :)
 - As with return types, a large percentage of these are likely to be
   gcc bugs, not yet reviewed.

Also, fix bug in handling of Ignore ABI type in argument lists.

is given, override the subtarget settings and enable 64-bit support.
This restores the earlier behavior, and fixes regressions on
Non-64-bit-capable x86-32 hosts.

This isn't necessarily the best approach, but the most obvious
alternative is to require -mcpu=x86-64 or -mattr=+64bit to be used
with -march=x86-64 when the host doesn't have 64-bit support. This
makes things little more consistent, but it's less convenient, and
it has the practical drawback of requiring lots of test changes, so
I opted for the above approach for now.

Duncan spotted this. Thanks!

accessed at least once as a vector.  This prevents it from
compiling the example in not-a-vector into:

define double @test(double %A, double %B) {
	%tmp4 = insertelement <7 x double> undef, double %A, i32 0
	%tmp = insertelement <7 x double> %tmp4, double %B, i32 4
	%tmp2 = extractelement <7 x double> %tmp, i32 4
	ret double %tmp2
}

instead, producing the integer code.  Producing vectors when they
aren't otherwise in the program is dangerous because a lot of other
code treats them carefully and doesn't want to break them down.
OTOH, many things want to break down tasty i448's.

operands also, this can mean that when we pop a node
off the list of nodes to be analyzed, it may already
have been analyzed.
