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

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.

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.

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
