Summary:
Adds the standard gauntlet of accessors for global indirect functions and updates the echo test.
Now it would be nice to have a target abstraction so one could know if they have access to a suitable ELF linker and runtime.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and

Normally, changing the function signatures of C APIs is disallowed,
but as these two are brand new last week, and haven't been released
yet, it is okay in this instance.
As per discussion in D56556, we will not add NameLen arguments to IR
building APIs, for the following reasons:
1. We do not want to deprecate all of the IR building APIs, just to add a
NameLen argument to each one.
2. Consistency is important, so adding it just to new ones is unfortunate.
3. The IR names are completely optional, useful for readability of IR
only. There is no value in ever supporting nul bytes.

With this change, the remaining `CallSite` usages are just for

This updates the C API for the removal of `TerminatorInst`. It converts
the type query to a predicate query and moves the generic methods to
work on `Instruction` instances that satisfy this predicate rather than
requiring a specific type. It also clarifies that the C API wrapping
`BasicBlock::getTerminator` just returns an `Instruction`. Because this
was always wrapped opaquely as a value and the functions consuming these
values will work on `Instruction` objects, this shouldn't break any
clients.
This is a completely compatible change to the C API.

The DEBUG() macro is very generic so it might clash with other projects.
The renaming was done as follows:
- git grep -l 'DEBUG' | xargs sed -i 's/\bDEBUG\s\?(/LLVM_DEBUG(/g'
- git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM
- Manual change to APInt
- Manually chage DOCS as regex doesn't match it.
In the transition period the DEBUG() macro is still present and aliased
to the LLVM_DEBUG() one.

OpenCL 2.0 introduces the notion of memory scopes in atomic operations to
global and local memory. These scopes restrict how synchronization is
achieved, which can result in improved performance.
This change extends existing notion of synchronization scopes in LLVM to
support arbitrary scopes expressed as target-specific strings, in addition to
the already defined scopes (single thread, system).
The LLVM IR and MIR syntax for expressing synchronization scopes has changed
to use *syncscope("<scope>")*, where <scope> can be "singlethread" (this
replaces *singlethread* keyword), or a target-specific name. As before, if
the scope is not specified, it defaults to CrossThread/System scope.
Implementation details:
- Mapping from synchronization scope name/string to synchronization scope id
is stored in LLVM context;
- CrossThread/System and SingleThread scopes are pre-defined to efficiently
check for known scopes without comparing strings;
- Synchronization scope names are stored in SYNC_SCOPE_NAMES_BLOCK in
the bitcode.

Original Patch and summary by Philip Reames.
RewriteStatepointsForGC tries to rewrite a function in a manner where
the optimizer can't end up using a pointer value after it might have
been relocated by a safepoint. This pass checks the invariant that
RSForGC is supposed to establish and that (if we constructed semantics
correctly) later passes must preserve.
This has been a really useful diagnostic tool when initially developing
the rewriting scheme and has found numerous bugs.

Summary:
This seems like an uncontroversial first step toward providing access to the metadata hierarchy that now exists in LLVM. This should allow for good debug info support from C.
Future plans are to deprecate API that take mixed bags of values and metadata (mainly the LLVMMDNode family of functions) and migrate the rest toward the use of LLVMMetadataRef.
Once this is in place, mapping of DIBuilder will be able to start.
