Also re-write how most of the directory indexing is done - as it has
grown over the years, it has become a bit of a mess and was overdue
for a cleanup.
Most importantly, this allows you to specify a directory with the
platform.plugin.darwin-kernel.kext-directories setting and now lldb
will search for kexts and kernels in those directories recursively.

Followup from r277778, after Mehdi's comments.
Expand %ld64 to perform the necessary preload instead, that way new
tests do not need to worry about setting up DYLD_INSERT_LIBRARIES
themselves.

For memset (and others) we can get diagnostics like:
struct stat { int x; };
void foo(struct stat *stamps) {
bzero(stamps, sizeof(stamps));
memset(stamps, 0, sizeof(stamps));
}
t.c:7:28: warning: 'memset' call operates on objects of type 'struct stat' while the size is based on a different type 'struct stat *' [-Wsizeof-pointer-memaccess]
memset(stamps, 0, sizeof(stamps));
~~~~~~ ^~~~~~
t.c:7:28: note: did you mean to dereference the argument to 'sizeof' (and multiply it by the number of elements)?
memset(stamps, 0, sizeof(stamps));
^~~~~~
This patch implements the same class of warnings for bzero.

The patch splits a complex && if condition into easier to read and understand
logic. That wrong early exit condition was letting some instructions with not
all operands available pass through when HoistingGeps was true.

Add a generalized IRBuilderCallbackInserter, which is just given a
callback to execute after insertion. This can be used to get rid of
the custom inserter in InstCombine, which will in turn allow me to add
target specific InstCombineCalls API for intrinsics without horrible
layering violations.

Shifts with a uniform but non-constant count were considered very expensive to
vectorize, because the splat of the uniform count and the shift would tend to
appear in different blocks. That made the splat invisible to ISel, and we'd
scalarize the shift at codegen time.
Since r201655, CodeGenPrepare sinks those splats to be next to their use, and we
are able to select the appropriate vector shifts. This updates the cost model to
to take this into account by making shifts by a uniform cheap again.

Summary:
The comparator function to compare input sections as instructed by
SORT command was a bit too complicated because it needed to handle
four different cases. This patch split it into two function calls.
This patch also simplifies the parser.

Green Dragon's darwin stage2 asan bot fails on some checks:

ERROR: Interceptors are not working. This may be because
AddressSanitizer is loaded too late (e.g. via dlopen)
To fix this, %ld64 needs to load 'libclang_rt.asan_osx_dynamic.dylib'
before libLTO.dylib, via DYLD_INSERT_LIBRARIES. This won't work by
updating config.environment, since some shim binary in the way scrubs
the env vars. Instead, provide the path to this lib through %asanrtlib,
which can then be used by tests directly with DYLD_INSERT_LIBRARIES.

when we are pointed at real data.
David Blaikie pointed out some odd logic in the case the Err value was a nullptr and
Lang Hames suggested it could be cleaned it up with an assert to know that Err is
not a nullptr when we are pointed at real data. As only in the case of constructing
the sentinel value by pointing it at null data is Err is permitted to be a nullptr,
since no error could occur in that case.
With this change the testing for “if (Err)” is removed from the constructor’s logic
and *Err is used directly without any check after the assert().

PR28848 had a very nice reduction of the underlying cause of the bug.
Our ValueMap had, in an entry for an Instruction, a ConstantInt.
This is not at all unexpected but should be handled properly.

This is the forth patch in the coroutine series. CoroEaly pass now lowers coro.resume
and coro.destroy intrinsics by replacing them with an indirect call to an address
returned by coro.subfn.addr intrinsic. This is done so that CGPassManager recognizes
devirtualization when CoroElide replaces a call to coro.subfn.addr with an appropriate
function address.

Our Report implementation calls OutputDebugString, which calls
RtlRaiseException, which can re-enter back into the ASan runtime and
cause a hang.
Don't treat this special debugger-only exception code as a noreturn
event, since the stack won't really unwind all the way.

CloneDetector should be able to detect clones with renamed variables.
However, if variables are referenced multiple times around the code sample,
the usage patterns need to be recognized.
For example, (x < y ? y : x) and (y < x ? y : x) are no longer clones,
however (a < b ? b : a) is still a clone of the former.
Variable patterns are computed and compared during a separate filtering pass.

Since the string table being read from the MachO is a properly bounded StringRef including null strings is safe and reasonable.

Summary:
The sanitizer allocators can works with a dynamic address space
(i.e. specified with ~0ULL).
Unfortunately, the code was broken on GetMetadata and GetChunkIdx.
The current patch is moving the Win64 memory test to a dynamic
address space. There is a migration to move every concept to a
dynamic address space on windows.
To have a better coverage, the unittest are now testing
dynamic address space on other platforms too.
