Previously the following code would warn on the use of "T":
template <typename T>
struct X {
typedef T *type;
};
...because nullability is /allowed/ on template parameters (because
they could be pointers). (Actually putting nullability on this use of
'T' will of course break if the argument is a non-pointer type.)
This fix doesn't handle the case where a template parameter is used
/outside/ of a typedef. That seems trickier, especially in parameter
position.

Because standard functions can be defined differently on different platforms,
this commit introduces a method for constructing summaries with multiple
variants, whichever matches better. It is also useful for supporting overloads.

DIHelper is a class having only one member, and ObjectFile has
a unique pointer to a DIHelper. So we can directly have ObjectFile
have the member.

This patch implements the register call calling convention, which ensures
as many values as possible are passed in registers. CodeGen changes
were committed in https://reviews.llvm.org/rL284108.

Summary:
As a unique_ptr or shared_ptr that has been moved from is guaranteed to be null,
we only warn if the pointer is dereferenced.

Otherwise we set it always to zero, which is not correct,
and we assert inside alignTo (Assertion failed:
Align != 0u && "Align can't be 0.").

Summary:
This patch allows the Darwin build to fall back to to Posix-style lookups for the clang resource directory if the debugger library isn't inside a framework.
The patch also includes a bit of refactoring and cleanup around the *nix resolution of the binary and lib directories to reuse the code instead of duplicating it.
With this patch Darwin builds that don't build a framework only have 3 failing tests on my system (TestExec.py).

Using a pattern similar to that of YamlIO, this allows
us to have a single codepath for translating codeview
records to and from serialized byte streams. The
current patch only hooks this up to the reading of
CodeView type records. A subsequent patch will hook
it up for writing of CodeView type records, and then a
third patch will hook up the reading and writing of
CodeView symbols.

Summary:
The post-RA scheduler occasionally uses additional implicit operands when
the vector implicit operand as a whole is killed, but some subregisters
are still live because they are directly referenced later. Unfortunately,
this seems incredibly subtle to reproduce.
Fixes piglit spec/glsl-110/execution/variable-indexing/vs-temp-array-mat2-index-wr.shader_test
and others.

This commit improves the "must have C++ linkage" error diagnostics that are
emitted for C++ declarations like templates and literal operators by adding an
additional note that points to the appropriate extern "C" linkage specifier.

Only tests using %clang_cl_asan were using the dynamic CRT before this.
The unit tests and lit tests using %clangxx_asan were using the static
CRT. Many cross-platform tests fail with the dynamic CRT, so I had to
add win32-(static|dynamic)-asan lit features.
Also deletes some redundant tests in TestCases/Windows that started
failing with this switch.

-shared-libasan is likely to be used as a link flag if the user is using
the GCC-style clang driver.
This logic is already tested in clang-cl tests, and the new flag to
exercise it will be covered by asan tests.

Summary:
Remove this pass from addMachineSSAOptimization() and register it unconditionally in through addPreRegAlloc(). This pass is required for generating correct PIC calls.

GPRC and GPRC_NOR0 (or the 64bit equivalent) and not just the latter.
GPRC_NOR0 contains ZERO as alternative meaning of r0 and is therefore
not a true subclass of GPRC.
