[CUDA] Raise an error if a wrong-side call is codegen'ed.
Summary:
Some function calls in CUDA are allowed to appear in
semantically-correct programs but are an error if they're ever
codegen'ed. Specifically, a host+device function may call a host
function, but it's an error if such a function is ever codegen'ed in
device mode (and vice versa).
Previously, clang made no attempt to catch these errors. For the most
part, they would be caught by ptxas, and reported as "call to unknown
function 'foo'".
Now we catch these errors and report them the same as we report other
illegal calls (e.g. a call from a host function to a device function).
This has a small change in error-message behavior for calls that were
previously disallowed (e.g. calls from a host to a device function).
Previously, we'd catch disallowed calls fairly early, before doing
additional semantic checking e.g. of the call's arguments. Now we catch
these illegal calls at the very end of our semantic checks, so we'll
only emit a "illegal CUDA call" error if the call is otherwise
well-formed.

Use -O1 when testing with ASAN and MSAN to prevent Clang OOM errors.
Currently certain tests get killed when compiled with ASAN at -O0 because
they eat all of the systems memory. This doesn't happen at -O1, so enable that
to work around the issue.

Split DescribeAddressIfShadow between a function that gets all the information, and one that prints it.
Summary:
Replacement for part of D23518
This is the first patch to start reifying information about errors. It deals only with reifying shadow address-related information.
It will allow us to generate structures with all the relevant information for a given error so a debugger can get to them or they can be included in a core dump.

Local variables whose address is taken and passed on to a call are described
in debug info using their stack slots instead of as an indirection of param reg + 0
offset. This is done by detecting FrameIndexSDNodes in SelectionDAG and generating
FrameIndexDbgValues for them. This ultimately generates DBG_VALUEs with stack
location operands.
