For EmulateInstructionARM::EmulatePUSH(), fix the logical branch for when pc is pushed to behave
like the other cases where:

    context.SetRegisterToRegisterPlusOffset (reg_info, sp_reg, addr - sp);

is called to inform of the operation to set a register value to a memory location calculated from
a base register plus an offset.

 - This is much more important than it appears at first glance...

The intended design of DiagnosticBuilder was that it never escape and that all
its members would get lowered to registers by the compiler. By fixing Emit here,
the compiler can completely eliminate the DiagnosticBuilder object and never
need to push those registers back into it.

Unfortunately, Sema has broken DiagnosticBuilder in other ways (by introducing
SemaDiagnosticBuilder), so we don't get the fill impact of this, but it is still
good for 30k reduction in code size. I'll work on fixing the
SemaDiagnosticBuilder problems next.

Previously, only diagnostics thrown by the cc1 process were
actually honoring the diagnostic options given on the command line,
like -Werror.

Reuse the existing code in Frontend currently used for cc1,
adjusting it to not interpret -Wl, linker flags as warnings.

Also fix a faulty test exposed by this change.
It wasn't actually testing anything, and was giving this warning:

clang-3: warning: argument unused during compilation: '-verify'

Which -Werror didn't turn into an error because it was output
by the driver, not the cc1 process, and diagnostic options
weren't parsed by the driver. And you couldn't see the warning
when running the test suite.

Fixes PR12181.

inlining to be the reverse of their declaration.

This optimizes running time under inlining up to 20% since we do not
re-analyze the utility functions which are usually defined first in the
translation unit if they have already been analyzed while inlined into
the root functions.

BFS should give slightly better performance. Ex: Suppose, we have two
roots R1 and R2. A callee function C is reachable through both. However,
C is not inlined when analyzing R1 due to inline stack depth limit. With
DFS, C will be analyzed as top level even though it would be analyzed as
inlined through R2. On the other hand, BFS could avoid analyzing C as
top level.

As a result:
 - We now analyze the C++ methods which are defined within the

from the .clear() of the SmallVector<FixItHint>, which does a std::~string, etc.
 - My understanding is we don't ever emit arbitrary numbers of fixits, so I just
   moved us to using a statically sized array like we do for arguments and
