Don't have both lldb and debugserver call waitpid on the target process.  This sets up a race condition,
and if lldb wins, then debugserver won't get the correct error status to lldb.

The sections .rela/.rel.(*) have a alignment of 2 in the final image created by
the linker. This needs to be properly set to the right alignment depending on
the architecture(32/64bits).

else.

Neither of these should have had any impact in practice.

to a variable.  This helps people figure out what
happened if they tried to do something to the variable
and it didn't work because we gave it the default type
of void*.

Doing some temporary touch-up on the gnu namespace attribute documentation, from a post-commit review comment.

Ideally, this content will eventually find a home with the rest of the attribute documentation.

This patch adds several built-ins that are required for ms 
compatibility. _mm_prefetch must be a built-in because it takes a 
compile-time constant argument and our prior approach of using a #define 
to the current built-in doesn't work in the presence of re-declaration 
of _mm_prefetch. The others can be obtained by including the windows 
system headers. If a user includes the windows system headers but not 
intrin.h they still need to work and therefore must be built-in because 
we don't get a chance to implement them in intrin.h in this case.

Until attribute documentation is implemented as a server-side feature, I will be manually committing AttributeReference.rst so that attribute documentation can be on the live server instead of simply disappearing from the language extensions page without obvious replacement.

This is a temporary stop-gap solution until server-side generation is implemented, at which point the AttributeReference.rst will go back to holding placeholder text.

Refactored the way attribute category headers are handled so that it is possible to use custom categories. This allows for moving the consumable attributes (consumable, callable_when, return_typestate, etc) to be grouped together, with a content heading, like they were in the language extensions documentation. Moved the consumable attribute documentation from the language extensions into the attribute documentation table.

This was broken because __has_include_next(...) would not be valid in a
preprocessor condition if __has_include_next is not defined.

This definition is not chosen idly. There is an unfortunate reality with
max_align_t -- the specific nature of its definition leaks into the ABI
almost immediately. Because it is part of C11 and C++11 it becomes
essential for it to match with other systems on that ABI. There is an
effort to discourage any further use of this construct as a consequence
-- using max_align_t introduces an immediate ABI problem. We can never
update it to have larger alignment even as the microarchitecture changes
to necessitate higher alignment. =/

The particular definition here exactly matches the ABI of GCC's chosen
::max_align_t definition, for better or worse. This was written with the
help of Richard Smith who was decoding the exact ABI implications of the
selected definition in GCC. Notably, in-register arguments are impacted
by the particular definition chosen. =/

No one is under the illusion that this is a "good" or "useful"
definition of max_align_t, and we are working with the standards
committee to specify a more useful interface to address this need.

In the Microsoft ABI, the vftable is laid out as if all methods in every
overload set were declared in reverse order of declaration at the point
of declaration of the first overload in the set.

Previously we only considered virtual methods in an overload set, but
MSVC includes non-virtual methods for ordering purposes.

Fixes PR18902.

TargetLoweringBase is implemented in CodeGen, so before this patch we had
a dependency fom Target to CodeGen. This would show up as a link failure of
llvm-stress when building with -DBUILD_SHARED_LIBS=ON.
