When CMAKE_SYSROOT or CMAKE_FIND_ROOT_PATH is set, cmake
recommends setting CMAKE_FIND_ROOT_PATH_MODE_INCLUDE=ONLY
globally which means find_path() always prepends CMAKE_SYSROOT or
CMAKE_FIND_ROOT_PATH to all paths used in the search.

However, these find_path() invocations are looking for paths in
the libcxx and libunwind projects on the host system, not the
target system, which can be done by passing
NO_CMAKE_FIND_ROOT_PATH.

For sections with different virtual and physical addresses, alignment and
placement in the output binary should be based on the physical address.

Ran into this problem with a bare metal ARM project where llvm-objcopy added a
lot of zero-padding before the .data section that had differing addresses. GNU
objcopy did not add the padding, and after this fix, neither does llvm-objcopy.

Update a test case so a section has different physical and virtual addresses.

Summary:
This patch removes IdentifierInfo from completion token after remembering
the identifier in the preprocessor.

Prior to this patch, completion token had the IdentifierInfo set to null when
completing at the start of identifier and to the II for completion prefix
when in the middle of identifier.

This patch unifies how code completion token is handled when it is insterted
before the identifier and in the middle of the identifier.

The actual IdentifierInfo can still be obtained from the Preprocessor.

Summary:
The existing option objc-property-declaration.Acronyms
replaces the built-in set of acronyms.

While this behavior is OK for clients that don't want the default
behavior, many clients may just want to add their own custom acronyms
to the default list.

This revision introduces a new option,
objc-property-declaration.IncludeDefaultAcronyms, which controls
whether the acronyms in objc-property-declaration.Acronyms are
appended to the default list (the default behavior) or whether they
replace.

I also updated the documentation.

The change in r322988 caused a failure in the bootstrap build bot.
The problem was that directly gluing a BR_CCMASK node to a
compare-and-swap could lead to issues if other nodes were
chained in between.  There is then no way to create a topological
sort that respects both the chain sequence and the glue property.

Fixed for now by rejecting the optimization in this case.  As a
future enhancement, we may be able to handle additional cases
by swapping chain links around.
