getAssociatedStmt() returns the outermost captured statement for the
OpenMP directive. It may return incorrect region in case of combined
constructs. Reworked the code to reduce the number of calls of
getAssociatedStmt() and used getInnermostCapturedStmt() and
getCapturedStmt() functions instead.
In case of firstprivate variables it may lead to an extra allocas
generation for private copies even if the variable is passed by value
into outlined function and could be used directly as private copy.

Fix makes the loop in LexAngledStringLiteral more like the loops in
LexStringLiteral, LexCharConstant. When we skip a character after
backslash, we need to check if we reached the end of the file instead of
reading the next character unconditionally.

It was never fully disallowed. We were rejecting it in the asm parser,
but not in the verifier.
Currently TargetMachine::shouldAssumeDSOLocal returns true for hidden
ifuncs. I considered changing it and moving the check from the asm
parser to the verifier.
The reason for deciding to allow it instead is that all linkers handle
a direct reference just fine. They use the plt address as the address
of the function. In fact doing that means that clang doesn't have the
same bug as gcc: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83782.
This patch then removes the check from the asm parser and updates the
bitcode reader and writer.

CMake insists that for each target, one uses only the non-keyword
version of target_link_library
target_link_library(mytarget lib)
or the one with PUBLIC/PRIVATE/INTERFACE keyword:
target_link_library(mytarget PUBLIC lib)
Otherwise, CMake fails with the error message:
The keyword signature for target_link_libraries has already been used with
the target "mytarget". All uses of target_link_libraries with a target
must be either all-keyword or all-plain.
Change all occurances of target_link_library to the newer keyworded
version to avoid such errors. Some already have been changed in r319840,
but might not be sufficient for all build configurations to build
the doxygen manual.

Part of the fix for https://bugs.llvm.org/show_bug.cgi?id=35812.
This patch ensures that the compare operand for the atomic compare and swap
is properly zero-extended to 32 bits if applicable.
A follow-up commit will fix the extension for the SETCC node generated when
expanding an ATOMIC_CMP_SWAP_WITH_SUCCESS. That will complete the bug fix.

Summary:
Enumerating the contents of a namespace or global scope will omit any
decls that aren't already loaded, instead of deserializing them from the
PCH.
This allows a fast hybrid code completion where symbols from headers are
provided by an external index. (Sema already exposes the information
needed to do a reasonabl job of filtering them).
Clangd plans to implement this hybrid.
This option is just a hint - callers still need to postfilter results if
they want to *avoid* completing decls outside the main file.

For hard float with VFP4, it is legal. Otherwise, we use libcalls.
This needs a bit of support in the LegalizerHelper for soft float
because we didn't handle G_FMA libcalls yet. The support is trivial, as
the only difference between G_FMA and other libcalls that we already
handle is that it has 3 input operands rather than just 2.

Currently, IRC contains `Begin` and `Step` as SCEVs and `End` as value.
Aside from that, `End` can also be `nullptr` which can be later conditionally
converted into a non-null SCEV.
To make this logic more transparent, this patch makes `End` a SCEV and
calculates it early, so that it is never a null.

Previously we checked (HeaderSize == 0) to find out if
PltSection section is IPLT or PLT. Some targets does not set
HeaderSize though. For example PPC64 has no lazy binding implemented
and does not set PltHeaderSize constant.
Because of that using of both IPLT and PLT relocations worked
incorrectly there (testcase is provided).

Summary:
Currently LLVM has no way to support configuring for IDE's like CLion. Like XCode and MSVC's IDE, CLion needs to see all of the headers and tablegen files in order to properly parse the sources.
This patch adds an `LLVM_ENABLE_IDE` option which can be used to configure for IDE's in general. It is used by `LLVMProcessSources.cmake` to determine if the extra source files should be added to the target.
Unfortunately because of the low level of `LLVMProcessSources.cmake`, I'm not sure where the `LLVM_ENABLE_IDE` option should live. I choose `HandleLLVMOptions.cmake` so that out-of-tree Clang builds would correctly configure the option by default.

RemoveInvalidLocations was clearing out the m_locations in the
breakpoint by hand, and it wasn't also clearing the locations from
the address->location map, which confused us when we went to update
breakpoint locations.
I also made Breakpoint::ModulesChanged check the Location's Section
to make sure it hadn't been deleted. This shouldn't strictly be necessary,
but if the DynamicLoaderPlugin doesn't do it's job right (I'm looking at
you new Darwin DynamicLoader...) then it can end up leaving stale locations
on rerun. It doesn't hurt to clean them up here as a backstop.
