Add a pass to lower is.constant and objectsize intrinsics
This pass lowers is.constant and objectsize intrinsics not simplified by
earlier constant folding, i.e. if the object given is not constant or if
not using the optimized pass chain. The result is recursively simplified
and constant conditionals are pruned, so that dead blocks are removed
even for -O0. This allows inline asm blocks with operand constraints to
work all the time.
The new pass replaces the existing lowering in the codegen-prepare pass
and fallbacks in SDAG/GlobalISEL and FastISel. The latter now assert
on the intrinsics.

LLVMGetInitializer returns nullptr in case there is no
initializer. There is not much that can be done with nullptr in OCaml,
not even test if it is null. Also, there does not seem to be a C or
OCaml API to test if there is an initializer. So this diff changes
Llvm.global_initializer to return an option.

DIFlagBlockByRefStruct is an unused DIFlag that originally was used by
clang to express (Objective-)C block captures in debug info. For the
last year Clang has been emitting complex DIExpressions to describe
block captures instead, which makes all the code supporting this flag
redundant.
This patch removes the flag and all supporting "dead" code, so we can
reuse the bit for something else in the future.
Since this only affects debug info generated by Clang with the block
extension this mostly affects Apple platforms and I don't have any
bitcode compatibility concerns for removing this. The Verifier will
reject debug info that uses the bit and thus degrade gracefully when
LTO'ing older bitcode with a newer compiler.

Introduce the debug info flag that indicates that a parameter has unchanged
value throughout a function. This info will be used to emit the expressions
with DW_OP_entry_value.

Add debug information accessors, as provided in the following patches:
https://reviews.llvm.org/D46627 (DILocation)
https://reviews.llvm.org/D52693 metadata kind
https://reviews.llvm.org/D60481 get/set debug location on a Value
https://reviews.llvm.org/D60489 (DIScope)
The API as proposed in this patch is similar to the current Value API,
with a single root type and methods that are only valid for certain
subclasses. I have considered just implementing generic Line() calls
(that are valid on all DINodes that have a line) but the implementation
of that got a bit awkward without support from the C API. I've also
considered creating generic getters like a Metadata.DebugLoc() that
returns a DebugLoc, but there is a mismatch between the Go DI nodes in
the LLVM API and the actual DINode class hierarchy, so that's also hard
to get right (without being confusing or breaking the API).

Add bindings so that predicates on comparisons (icmp/fcmp) can be
inspected from IR.
Note: I considered adding Value.ICmpPredicate() etc. instead but
Value.IntPredicate() seemed easier to read and matches the name of the
returned type.
(This change was also pushed two commits ago but accidentally had the
wrong title and description.)

This is the second attempt to port ASan to new PM after D52739. This takes the
initialization requried by ASan from the Module by moving it into a separate
class with it's own analysis that the new PM ASan can use.
Changes:
- Split AddressSanitizer into 2 passes: 1 for the instrumentation on the
function, and 1 for the pass itself which creates an instance of the first
during it's run. The same is done for AddressSanitizerModule.
- Add new PM AddressSanitizer and AddressSanitizerModule.
- Add legacy and new PM analyses for reading data needed to initialize ASan with.
- Removed DominatorTree dependency from ASan since it was unused.
- Move GlobalsMetadata and ShadowMapping out of anonymous namespace since the
new PM analysis holds these 2 classes and will need to expose them.

The test started failing for me recently. I don't see any changes around
this code, so maybe it's my local go version that changed or something.
The error seems real to me: we're trying to print an Attribute with %d.
The test talks about "attribute masks" I'm not sure what that refers to,
but I suppose we could print the raw pointer value, since that's
what the test seems to be comparing.

to reflect the new license.
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
repository.

Summary:
Second iteration of D56433 which got reverted in rL350719. The problem
in the previous version was that we dropped the thunk calling the tsan init
function. The new version keeps the thunk which should appease dyld, but is not
actually OK wrt. the current semantics of function passes. Hence, add a
helper to insert the functions only on the first time. The helper
allows hooking into the insertion to be able to append them to the
global ctors list.

Summary:
Keeping msan a function pass requires replacing the module level initialization:
That means, don't define a ctor function which calls __msan_init, instead just
declare the init function at the first access, and add that to the global ctors
list.
Changes:
- Pull the actual sanitizer and the wrapper pass apart.
- Add a newpm msan pass. The function pass inserts calls to runtime
library functions, for which it inserts declarations as necessary.
- Update tests.
Caveats:
- There is one test that I dropped, because it specifically tested the
definition of the ctor.

Summary: This instruction is useful for inspecting extractvalue/insertvalue in IR. Unlike most other operations, indices cannot be inspected using the generic Value.Opcode() function so a specialized function needs to be added.
