This recommits r341472, which was reverted due to test failures on macos bots.
The issue was that a macos target implies -glldb which, together with
this patch added a -gpubnames switch where there previously wasn't one.
The intentions of those checks was to check that -gpubnames is not
emitted by default so I add an explicit -ggdb arg to those command lines
to get same behavior on all platforms (the fact that -glldb *does* set
-gpubnames is tested by a separate test).

Summary:
Negative arguments in kernel attributes are silently bitcast'ed to
unsigned, for example:
__attribute__((reqd_work_group_size(1, -1, 1)))
__kernel void k() {}
is a complete equivalent of:
__attribute__((reqd_work_group_size(1, 4294967294, 1)))
__kernel void k() {}
This is likely an error, so the patch forbids negative arguments in
several OpenCL attributes. Users who really want 4294967294 can still
use it as an unsigned representation.

destructors.
We previously tried to patch up the exception specification after
completing the class, which went wrong when the exception specification
was needed within the class body (in particular, by a friend
redeclaration of the destructor in a nested class). We now mark the
destructor as having a not-yet-computed exception specification
immediately after creating it.
This requires delaying various checks against the exception
specification (where we'd previously have just got the wrong exception
specification, and now find we have an exception specification that we
can't compute yet) when those checks fire while the class is being
defined.
This also exposed an issue that we were missing a CodeSynthesisContext
for computation of exception specifications (otherwise we'd fail to make
the module containing the definition of the class visible when computing
its members' exception specs). Adding that incidentally also gives us a
diagnostic quality improvement.
This has also exposed an pre-existing problem: making the exception
specification evaluation context a non-SFINAE context (as it should be)
results in a bootstrap failure; PR38850 filed for this.

Load Hardening.
Wires up the existing pass to work with a proper IR attribute rather
than just a hidden/internal flag. The internal flag continues to work
for now, but I'll likely remove it soon.
Most of the churn here is adding the IR attribute. I talked about this
Kristof Beyls and he seemed at least initially OK with this direction.
The idea of using a full attribute here is that we *do* expect at least
some forms of this for other architectures. There isn't anything
*inherently* x86-specific about this technique, just that we only have
an implementation for x86 at the moment.
While we could potentially expose this as a Clang-level attribute as
well, that seems like a good question to defer for the moment as it
isn't 100% clear whether that or some other programmer interface (or
both?) would be best. We'll defer the programmer interface side of this
for now, but at least get to the point where the feature can be enabled
without relying on implementation details.
This also allows us to do something that was really hard before: we can
enable *just* the indirect call retpolines when using SLH. For x86, we
don't have any other way to mitigate indirect calls. Other architectures
may take a different approach of course, and none of this is surfaced to
user-level flags.

Summary:
Some `Expr` classes set up default values for the `ExprBits` of `Stmt`. These
default values are then overwritten by the parser sometimes. One example is
`InitListExpr` which sets the value kind to be an rvalue in the ctor. However,
this bit may change after the `InitListExpr` is created. There may be other
expressions similar to `InitListExpr` in this sense, thus the safest solution
is to copy the expression bits.
The lack of copying `ExprBits` causes an assertion in the analyzer engine in a
specific case: Since the value kind is not imported, the analyzer engine
believes that the given InitListExpr is an rvalue, thus it creates a
nonloc::CompoundVal instead of creating memory region (as in case of an lvalue
reference).

When compiling CUDA or OpenMP device code Clang parses header files
that expect certain predefined macros from the host architecture. To
make this work the compiler passes the host triple via the -aux-triple
argument and (until now) pulls in all macros for that "auxiliary triple"
unconditionally.
However this results in defines like __SSE_MATH__ that will trigger
inline assembly making use of the "advertised" target features. See
the discussion of D47849 and PR38464 for a detailed explanation of
the encountered problems.
Instead of blacklisting "known bad" examples this patch starts adding
defines that are needed for certain headers like bits/wordsize.h and
bits/mathinline.h.
The disadvantage of this approach is that it decouples the definitions
from their target toolchain. However in my opinion it's more important
to keep definitions for one header close together. For one this will
include a clear documentation why these particular defines are needed.
Furthermore it simplifies maintenance because adding defines for a new
header or support for a new aux-triple only needs to touch one piece
of code.

Revert to the original behavior: only calculate real file path when
file is opened and avoid using InterndPath for real path calculation.

Summary:
This partially rolls back the change in D48903:
89aa7f45a1 (diff-0025af005307891b5429b6a834823d5eR318)
`real_path` can be very expensive on real file systems, and calling it on each
opened file can slow down the compilation. This also slows down deserialized
ASTs for which real paths need to be recalculated for each input files again.
For clangd code completion latency (using preamble):

Lands r340468 again, but this time we mark the test as unsupported on Windows
because it seems that try/catch crashes CodeGen at the moment.

Summary:
This patch implements a new cache for the result of SMT queries; with this patch the regression tests are 25% faster.
It's implemented as a `llvm::DenseMap` where the key is the hash of the set of the constraints in a state.
There is still one method that does not use the cache, `getSymVal`, because it needs to get a symbol interpretation from the SMT, which is not cached yet.

llvm-svn: 340535
Summary:
With this patch, the SMT backend is almost completely detached from the CSA.
Unfortunate consequence is that we missed the `ConditionTruthVal` from the CSA and had to use `Optional<bool>`.
The Z3 solver implementation is still in the same file as the `Z3ConstraintManager`, in `lib/StaticAnalyzer/Core/Z3ConstraintManager.cpp` though, but except for that, the SMT API can be moved to anywhere in the codebase.
