Fixed a bug where we'd emit multiple diagnostics if there was a problem
taking the address of an overloaded template function.

This was a minor bug in r249492. Calling PrepareEHLandingPad on a
non-landingpad was a no-op, but it attempted to get the generic pointer
register class, which apparently doesn't exist for some targets.

Summary:
Many small improvements to LLVM_BUILD_EXTERNAL_COMPILER_RT.
* Works correctly with Ninja by working around CMake Bug 14771 (https://cmake.org/Bug/view.php?id=14771)
* Has install-compiler-rt target, and installs as part of the default install target
* Sets the install paths properly so that it matches the non-standalone build
* Only generate the test targets if(LLVM_INCLUDE_TESTS)

In order to actually verify the condition, we have to use a weak symbol.
If an undefined symbol is not used at all, it is naturally ignored not by
the code for --as-needed but by the code for something else.

This is a more principled version of what I did earlier. Path
normalization is generally a good thing, but may break users in strange
environments, e. g. using lots of symlinks. Let the user choose and
default it to on.
This also changes adding a duplicated file into returning an error if
the file contents are different instead of an assertion failure.

On targets where f32 is not legal, we have to look through a BITCAST SDNode to
find the register that an argument is stored in when emitting debug info, or we
will not be able to emit a DW_AT_location for it.

On Windows, fs::rename() could fail is another process was reading the
file at the same time using fs::openFileForRead(). In most cases the user
wouldn't notice as fs::rename() will continue to retry for 2000ms. Typically
this is enough for the read to complete and a retry to succeed, but if the
disk is being it too hard then the response time might be longer than the
retry time and the rename would fail with a permission error.
Add FILE_SHARE_DELETE to the sharing flags for CreateFileW() in
fs::openFileForRead() and try ReplaceFileW() prior to MoveFileExW()
in fs::rename().
Based on an initial patch by Edd Dawson!

Summary:
This removes unnecessary instructions when extracting from an undefined register
and also fixes a crash for O32 when passing undef to a double argument in
held in integer registers.

Summary:
Test decorators were ignoring AttributeError exceptions. These were introduced three years ago,
and copied to all decorators. They seem to serve no purpose and removing them produces no errors.
Given that they have prevented us from noticing the problem in r249819, I am removing them.

Actually the only special path we have to handle is ./foo, the rest is
tricky to get right so do the same thing as the existing YAML vfs here.

GlobalOpt currently merges stores into the initialisers of internal,
externally_initialized globals, but should not do so as the value of the global
may change between the initialiser and any code in the module being run.

The Swift Machine Scheduler Model is incomplete. There are instructions
missing which can trigger the "incomplete machine model" abort. This was
observed when a downstream SchedMachineModel was added to the ARM
target.
