Atom ordinals are the indeces in a file. Currently the PECOFF reader assigns
ordinals for each section, so it's (incorrectly) assigning duplicate ordinals.

Enabling the subject list for the warn_unused attribute, and adding a test case. Previously, would issue a "warning ignored" diagnostic instead of the more specific "only applies to."

We currently error in clang with:
"error: thread-local storage is unsupported for the current target", but we
can start to get the llvm level ready.

When compiling

template<typename T>
struct foo {
  static __declspec(thread) int bar;
};
template<typename T>
__declspec(therad) int foo<T>::bar;
template struct foo<int>;

msvc produces

gcc produces a ".data$__emutls_v.<symbol>" for the testcase with
__declspec(thread) replaced with thread_local.

Refactored semantic handlers that would unilaterally apply the attribute to a Decl so they all go through a common interface. No functional change intended.

MO_ConstantPoolIndex is handled in printLeaMemReference.

Removing the description part of a subset subject. It is unused, and wouldn't be future-proof regarding translation issues. It is also covered by SubjectList's CustomDiag member.

Laying the basic groundwork for table generating the diagnostics for attribute subjects. This makes some modifications to the way subjects are listed in Attr.td, and updates the attr emitter to handle the new constructs.

I have disabled some attribute subject lines on purpose in Attr.td;
this part is a WIP with the goal being to restore those subjects
incrementally. By commenting them out, it leaves the original behavior
the same as before for those attributes and so those are not
functionality changes.

More steps are needed to actually make it usable:
* sanitizer runtimes should be compiled with -DSANITIZER_LIBBACKTRACE.
* libbacktrace headers should be installed.
* user has to manually link in libbacktrace.a into the executable.

We can easily solve the first two problems in the build system, but
detecting/linking libbacktrace to all the tests we have and end-user programs
is more challenging (and will unlikely work w/o Driver support).

This commit embeds a set of linker flags with hardcoded paths to
the LLVM shared library on --enable-shared builds into .cmxa files
and stub dynamic libraries. This solution closely follows existing
rules for rpath in the LLVM tools, which had to be modified because
of differences in toolchain.

Without this patch, OCaml tests as well as opam bindings broke,
as neither of those updates LD_LIBRARY_PATH to include
the $prefix/lib directory.

We would fail to instantiate them when the surrounding function was
instantiated. Instantiate the class and add it's members to the list of
pending instantiations, they should be resolved when we are finished
with the function's body.

This fixes PR9685.

It is only used for asm printing.

On X86 we put basic block addresses on register before passing them to inline
asm, so the MO_MachineBasicBlock case was dead.

MO_ExternalSymbol was dead since any symbol being passed to inline asm
is represented as MO_GlobalAddress.

The MO_GlobalAddress and MO_Register cases were not tested.

look at the attribute spelling instead. The 'ownership_*' attributes should
probably be split into separate *Attr classes, but that's more than I wanted to
do here.
