When testing against the system library, there is a relatively minor
ABI breakage that the std::future_errc values have been changed to
avoid using zero. Update the tests that rely on the values being
consistent.

This undoes half of r208786.
It had problems with lazily declared special members in cases like this:
struct A {
A();
A &operator=(A &&o);
void *p;
};
void foo(A);
void bar() {
foo({});
}
In this case, the copy and move constructors are implicitly deleted.
However, Clang doesn't eagerly declare the copy ctor in the AST, so we
pass the struct in registers. Furthermore, GCC passes this in registers
even though this class should be uncopyable.
Revert this for now until the dust settles.

These tests haven't been failing on darwin11 or 12 since r189610 when
pr17027 was fixed, but they've been keeping the libc++ bot red by
XPASSing since then.

Summary:
This gets rid of a sub instruction by moving the negation to the
constant when valid.

Abstract variables should never have/use locations. In this case the
data wasn't used, so no functional change intended here, just
simplification.

ExportedSymbolRenameFile is not always used. In most cases we don't
need to read given files at all. So lazy load would help. This doesn't
change the meaining of the program.

Many old tests using prior schemas still had some brokenness here (both
indirect arrays and arrays with single bogus elements). Fixed those up
so they don't hit the new assertions.
Also reduced nesting in some places, etc.

This is just unneccessary - we only create abstract definitions when
we're inlining anyway, so there's no reason to delay this to see if
we're going to inline anything.

In r205566, I made a change to Resolver so that Resolver revisit
only archive files in --start-group and --end-group pair. That's
not correct, as it also has to revisit DSO files.
This patch is to fix the issue.
Added a test to demonstrate the fix. I confirmed that it succeeded
before r205566, failed after r205566, and is ok with this patch.

If the function has the landingpad instruction, then the
handlerdata should be emitted even if the function has
nouwnind attribute. Otherwise, following code will not
work:
void test1() noexcept {
try {
throw_exception();
} catch (...) {
log_unexpected_exception();
}
}
Since the cantunwind was incorrectly emitted and the
LSDA is not available.

The commit r208166 will cause some regression on ARM EHABI.
This fix has been committed in r208715, and an assertion failure
test case has been committed in r208770.
This commit further extends the unittest so that the actual
value in the handlerdata will be checked.
