Removing more :option: tags that we do not have corresponding .. option directives for; these are causing the sphinx bot to fail (http://lab.llvm.org:8011/builders/clang-sphinx-docs/builds/15195/steps/docs-clang-html/logs/stdio).

This is a malformed :option: tag -- we don't have an option directive that matches it, so turning it actual text instead of a markup tag. This will hopefully fix the clang docs build (http://lab.llvm.org:8011/builders/clang-sphinx-docs/builds/15194/steps/docs-clang-html/logs/stdio)

rL275318 added the test Frontend/opencl.cl test, but that test was never actually run because Frontend/lit.local.cfg doesn't contain the '.cl' file suffix.

Once the test is activated, it fails with (unintended) compile errors in the newly added CHECK_INVALID_OPENCL_VERSION checks.

This patch adds the '.cl' file suffix to Frontend/lit.local.cfg to activate the test and fixes the test bug by adding '-fblocks' to the relevant command lines.

-fxray-instruction-threshold: configures the threshold for function size (looking at IR instructions), and allow LLVM to decide whether to add the nop sleds later on in the process.

This patch is similar to the implementation of 'private' clause: it adds a list of private pointers to be used within the target data region to store the device pointers returned by the runtime.
Please refer to the following document for a full description of what the runtime witll return in this case (page 10 and 11):
https://github.com/clang-omp/OffloadingDesign

I am happy to answer any question related to the runtime interface to help reviewing this patch.

On Linux, if the timestamp of a header file, included in the pch, is modified, then including the pch without regenerating it causes a fatal error, which is reasonable.
On Windows the check is ifdefed out, allowing the compilation to continue in a broken state.
The root of the broken state is that, if timestamps dont match, the preprocessor will reparse a header without discarding the pch data.
This leads to "#pragma once" header to be included twice.
The reason behind the ifdefing of the check lacks documentation, and was done 6 years ago.
This change tentatively removes the ifdefing.

Summary:
Bug pointed out by Benjamin Kramer in r264008.  I think the bug is
benign because by the time this is called, we should only have at most
two overloads to consider (either a host and a device overload, or a
host+device overload, but not all three).
