function templates as well.
A future commit will mangle the added name with the template args
like classes are mangled.

"struct{template struct{" would fail an assertion.
This assertion failure seems to have gone away somewhere along the line so
here's a test to make sure we don't regress. We still accept some very weird
explicit template 'instantiations' ("template int;", anyone) but at least we're
not asserting/crashing here.

Simplify the locking strategy for Module and its owned objects to always use the Module's mutex to avoid A/B deadlocks. We had a case where a symbol vendor was locking itself and then calling a function that would try to get it's Module's mutex and at the same time another thread had the Module mutex that was trying to get the SymbolVendor mutex. Now any classes that inherit from ModuleChild should use the module lock using code like:
void
ModuleChildSubclass::Function
{
ModuleSP module_sp(GetModule());
if (module_sp)
{
lldb_private::Mutex::Locker locker(module_sp->GetMutex());
... do work here...
}
}
This will help avoid deadlocks by using as few locks as possible for a module and all its child objects and also enforce detecting if a module has gone away (the ModuleSP will be returned empty if the weak_ptr does refer to a valid object anymore).

(i16 load $addr+c*sizeof(i16)) and replace uses of (i32 vextract) with the
i16 load. It should issue an extload instead: (i32 extload $addr+c*sizeof(i16)).

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.

AnalysisConsumer.
As a result:
- We now analyze the C++ methods which are defined within the
class body. These were completely skipped before.
- Ensure that AST checkers are called on functions in the
order they are defined in the Translation unit.

by ~%.3/~100k in my build -- simply by eliminating the horrible code bloat coming
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
ranges.
