To simplify source location offsets, this test uses line directives to
force particular lines of interest to have known line numbers so that
adjustments before/after those points don't require updates to the CHECK
lines.

Summary:
Previously, we would generate a single name for all reference
temporaries and allow LLVM to rename them for us.  Instead, number the
reference temporaries as we build them in Sema.

Fixing a cast-qual warning. getBufferStart() and getBufferEnd() both return a const char *, so casting to non-const was triggering a warning (even though the assignment and usage was always const anyway).

We accept 'void *p; p->~void();' for MSVC compatibility since r148682.
However, we were returning ExprError, rather than producing an AST,
despite only diagnosing it with a warning.  CodeGen noticed that the
template function specialization had an invalid AST, and therefore
didn't generate code for it.  This change makes us produce an AST with a
void pseudo-dtor call.

Part of PR18256.

In general the linker scripts's GROUP command works like a pair
of command line options --start-group/--end-group. But there is
a difference in the files look up algorithm.

The --start-group/--end-group commands use a trivial approach:
a) If the path has '-l' prefix, add 'lib' prefix and '.a'/'.so'
   suffix and search the path through library search directories.
b) Otherwise, use the path 'as-is'.

The GROUP command implements more compicated approach:
a) If the path has '-l' prefix, add 'lib' prefix and '.a'/'.so'
   suffix and search the path through library search directories.
b) If the path does not have '-l' prefix, and sysroot is configured,
   and the path starts with the / character, and the script being
   processed is located inside the sysroot, search the path under
   the sysroot. Otherwise, try to open the path in the current
   directory. If it is not found, search through library search
   directories.

"1" means entering a new file (from a different one), but the main
file is not included from anything (and this would e.g. confuse -Wunused-macros
to not report unused macros in the main file, see pr15610, or also see pr18948).
The line marker is still useful e.g. if the resulting file is renamed or used
via a pipe.

We currently force symbols to be globals in .thumb_set. The intent
seems to be that given

.thumb_set foo, bar

we emit an undefined symbol to bar if it is never defined. The side
effect is that we mark bar as global, even if it is defined, which gas
does not.

Producing an undefined reference to bar is a general difference from MC and gas.
For example, given

a = b

gas will produce an undefined reference to b, MC will not. I would be surprised
if any code depends on this, but it it does, we should fix the general
difference, not special case .thumb_set.

Enclosing the original #include directive inside #if 0 adds lines,

This fixes an ARM assembler crash - regression test added.

=[

Turns out that this was the root cause of PR19621. We found a crasher
only recently (likely due to improvements elsewhere in the SLP
vectorizer) but the reduced test case failed all the way back to here.
I've confirmed that reverting this patch both fixes the reduced test
case in PR19621 and the actual source file that led to it, so it seems
to really be rooted here. I've replied to the commit thread with
discussion of my (feeble) attempts to debug this. Didn't make it very
far, so reverting now that we have a good test case so that things can
get back to healthy while the debugging carries on.

removal. We can't just blindly increment (or decrement) the adapted
iterator when the value is null because doing so can walk past the end
(or beginning) and keep inspecting the value. The fix I've implemented
is to restrict this further to a forward iterator and add an end
iterator to the members (replacing a member that had become dead when
I switched to the adaptor base!) and using that to stop the iteration.

I'm not entirely pleased with this solution. I feel like forward
iteration is too restrictive. I wasn't even happy about bidirectional
iteration. It also makes the iterator objects larger and the iteration
loops more complex. However, I also don't really like the other
alternative that seems obvious: a sentinel node. I'm still hoping to
come up with a more elegant solution here, but this at least fixes the
MSan and Valgrind errors on this code.

Summary:
There are two functional changes:
1) The directive is not expanded for the ASM->ASM code path.
2) If PIC is not set, there's no expansion for the ASM->OBJ code path (same behaviour as GAS).
