[ARM] Clear the constant pool cache on explicit .ltorg directives
Multiple ldr pseudoinstructions with the same constant value will
reuse the same constant pool entry. However, if the constant pool
is explicitly flushed with a .ltorg directive, we should not try
to reference constants in the previous pool any longer, since they
may be out of range.
This fixes assembling hand-written assembler source which repeatedly
loads the same constant value, across a binary size larger than the
pc-relative fixup range for ldr instructions (4096 bytes). Such
assembler source already uses explicit .ltorg instructions to emit
constant pools with regular intervals. However if we try to reuse
constants emitted in earlier pools, they end up out of range.
This makes the output of the testcase match what binutils gas does

[libc++] Implement exception_ptr on Windows
Summary:
This patch implements exception_ptr on Windows using the `__ExceptionPtrFoo` functions provided by MSVC.
The `__ExceptionPtrFoo` functions are defined inside the C++ standard library, `msvcprt`, which is unfortunate because it requires libc++ to link to the MSVC STL. However this doesn't seem to cause any immediate problems. However to be safe I kept all usages within the libc++ dylib so that user programs wouldn't have to link to MSVCPRT as well.
Note there are still 2 outstanding exception_ptr/nested_exception test failures.
* `current_exception.pass.cpp` needs to be rewritten for the Windows exception_ptr semantics which copy the exception every time.
* `rethrow_if_nested.pass.cpp` need investigation. It hits a stack overflow, likely from recursion.
This patch also gets most of the `<future>` tests passing as well.

Currently llvm-rtdyld in -check mode will map sections to back-to-back 4k
aligned slabs starting at 0x1000. Automatically remapping sections by default is
helpful because it quickly exposes relocation bugs due to use of local addresses

[Analysis] Print out unreachable loops
Summary:
When writing a loop pass I made a mistake and hit the assertion
"Unreachable block in loop". Later, I hit an assertion when I called
`BasicBlock::eraseFromParent()` incorrectly: "Use still stuck around
after Def is destroyed". This latter assertion, however, printed out
exactly which value is being deleted and what uses remain, which helped
me debug the issue.
To help people debugging their loop passes in the future, print out
exactly which basic block is unreachable in a loop.

[LazyValueInfo] Avoid unnecessary copies of ConstantRanges
Summary:
ConstantRange contains two APInts which can allocate memory if their width is larger than 64-bits. So we shouldn't copy it when we can avoid it.
This changes LVILatticeVal::getConstantRange() to return its internal ConstantRange by reference. This allows many places that just need a ConstantRange reference to avoid making a copy.
Several places now capture the return value of getConstantRange() by reference so they can call methods on it that don't need a new object.
Lastly it adds std::move in one place to capture to move a local ConstantRange into an LVILatticeVal.

Add support for building modules from preprocessed source.
To support this, an optional marker "#pragma clang module contents" is
recognized in module map files, and the rest of the module map file from that
point onwards is treated as the source of the module. Preprocessing a module
map produces the input module followed by the marker and then the preprocessed
contents of the module.
Ignoring line markers, a preprocessed module might look like this:
module A {
header "a.h"
}
#pragma clang module contents
#pragma clang module begin A
// ... a.h ...
#pragma clang module end
The preprocessed output generates line markers, which are not accepted by the
module map parser, so -x c++-module-map-cpp-output should be used to compile
such outputs.
A couple of major parts do not work yet:
1) The files that are listed in the module map must exist on disk, in order to
build the on-disk header -> module lookup table in the PCM file. To fix
this, we need the preprocessed output to track the file size and other stat
information we might use to build the lookup table.
2) Declaration ownership semantics don't work properly yet, since mapping from
a source location to a module relies on mapping from FileIDs to modules,
which we can't do if module transitions can occur in the middle of a file.
