This avoids the need for a custom generated config file which is desired
because the custom config files differs per-target which means we cannot
reuse headers across different targets.

With -fno-plt, for example, calls to printf when getting converted to puts
still use the PLT. This patch checks for the metadata "RtLibUseGOT" and
annotates the declaration with the right attributes.

ds_read_b128 and ds_write_b128 have been recently enabled
under the amdgpu-ds128 option because the performance benefit
is unclear.
Though, using 128-bit loads/stores for the local address space
appears to introduce regressions in tessellation shaders. Not
sure what is broken, but as ds_read_b128/ds_write_b128 are not
enabled by default, just introduce a global option and enable
128-bit only if requested (until it's fixed/used correctly).
v2: - fix regressions in merge-stores.ll and multiple_tails.ll

Summary:
When inserting MOVs to avoid Falkor HWPF collisions, the non-base
register operand of load instructions (e.g. a register offset) was not
being considered live, so it could potentially have been used as a
scratch register, clobbering the actual offset value.

Summary:
The verification rules for the intrinsics for atomic memcpy, atomic memmove,
and atomic memset are basically code clones. This change merges their verification
rules into a single block to remove duplication.

Darwin dynamic linker can handle weak symbols in ConstDataSection.

This allows toolchain drivers to add multiple libc++ include paths akin
to libstdc++. This is useful in multiarch setup when some headers might
be in target specific include directory. There should be no functional

Summary:
A simple refactor to remove duplicate code in the definitions of
MemSetInst, AtomicMemSetInst, and AnyMemSetInst. Introduce a
templated base class that contains all of the methods unique to
a memset intrinsic, and derive these three classes from that.

This commit fixes the bot failures that were coming up before with r329716.
The fix was to move the check for "isInSection()" inside of the if condition
and emit the error there instead of waiting to get past the unreachable statement.
This should work in debug and release builds now.

This test ensures the popfd instruction in MS inline assembly can properly find a clobber name for the dirflag register. Previously the register was named 'DF', but it needs to be named 'dirflag' to match the name in the GCC register name list.

Currently we always include PTX into the fatbin along
with the GPU code.It about doubles the size of the GPU binary
we need to carry in the executable. These options allow control
inclusion of PTX into GPU binary.
This patch does not change the defaults, though we may consider
making no-PTX the default in the future.

In `ParseDeclarationSpecifiers` for the code
class A typename A;
we were able to annotate token `kw_typename` because it refers to
existing type. But later during processing token `annot_typename` we
failed to `SetTypeSpecType` and exited switch statement leaving
annotation token unconsumed. The code after the switch statement failed
because it didn't expect a special token.
The fix is not to assume that switch statement consumes all special
tokens and consume any token, not just non-special.

Summary:
It is possible that there will be two different instantiations of
the printer template for a given type and some tests could end up calling the
wrong (default) one. For example, it was seen in CodeCompleteTests.cpp when
printing CompletionItems that it would use the wrong printer because the default
is also instantiated in ClangdTests.cpp.
With this change, objects that were previously printed with a custom Printer now
get printed through the operator<< which is declared alongside the class.
This rule of the thumb should make it less error-prone.
