As requested in D115787, I've added a test for LLVMConstGEP2 and

I also had to change a couple of APIs to work on GEP operators,
rather than only GEP instructions.

This patch changes the AArch32 crypto instructions (sha2 and aes) to
require the specific sha2 or aes features. These features have
already been implemented and can be controlled through the command
line, but do not have the expected result (i.e. `+noaes` will not
disable aes instructions). The crypto feature retains its existing
meaning of both sha2 and aes.
Several small changes are included due to the knock-on effect this has:
- The AArch32 driver has been modified to ensure sha2/aes is correctly
set based on arch/cpu/fpu selection and feature ordering.
- Crypto extensions are permitted for AArch32 v8-R profile, but not
enabled by default.
- ACLE feature macros have been updated with the fine grained crypto
algorithms. These are also used by AArch64.
- Various tests updated due to the change in feature lists and macros.

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.

This adds support for scalable vector types in the C API and in
llvm-c-test, and also adds a test to ensure that llvm-c-test can properly
roundtrip operations involving scalable vectors.
While creating this diff, I discovered that the C API cannot properly roundtrip
_constant expressions_ involving shufflevector / scalable vectors, but that
seems to be a separate enough issue that I plan to address it in a future diff
(unless reviewers feel it should be addressed here).

D70365 allows us to make attributes default. This is a follow up to
actually make nosync, nofree and willreturn default. The approach we
chose, for now, is to opt-in to default attributes to avoid introducing
problems to target specific intrinsics. Intrinsics with default
attributes can be created using `DefaultAttrsIntrinsic` class.
This commit fixes a regression (from LLVM 10 to LLVM 11 RC3) in the LLVM
C API.
Previously, commit 1ee6ec2bf removed the mask operand from the
ShuffleVector instruction, storing the mask data separately in the
instruction instead; this reduced the number of operands of
ShuffleVector from 3 to 2. AFAICT, this change unintentionally caused
a regression in the LLVM C API. Specifically, it is no longer possible
to get the mask of a ShuffleVector instruction through the C API. This
patch introduces new functions which together allow a C API user to get
the mask of a ShuffleVector instruction, restoring the functionality
which was previously available through LLVMGetOperand().
This patch also adds tests for this change to the llvm-c-test
executable, which involved adding support for InsertElement,
ExtractElement, and ShuffleVector itself (as well as constant vectors)
to echo.cpp. Previously, vector operations weren't tested at all in
echo.ll.
I also fixed some typos in comments and help-text nearby these changes,
which I happened to spot while developing this patch. Since the typo
fixes are technically unrelated other than being in the same files, I'm
happy to take them out if you'd rather they not be included in the patch.

Summary:
This is the InlineAdvisor used in 'development' mode. It enables two
scenarios:
- loading models via a command-line parameter, thus allowing for rapid
training iteration, where models can be used for the next exploration
phase without requiring recompiling the compiler. This trades off some
compilation speed for the added flexibility.
- collecting training logs, in the form of tensorflow.SequenceExample
protobufs. We generate these as textual protobufs, which simplifies
generation and testing. The protobufs may then be readily consumed by a
tensorflow-based training algorithm.
To speed up training, training logs may also be collected from the
'default' training policy. In that case, this InlineAdvisor does not
use a model.

The DW_AT_LLVM_sysroot attribute is used for Clang module debug info,
to allow LLDB to import a Clang module from source. Currently it is
part of each DW_TAG_module, however, it is the same for all modules in
a compile unit. It is more efficient and less ambiguous to store it
once in the DW_TAG_compile_unit.
This should have no effect on DWARF consumers other than LLDB.
Differential Revision: https://reviews.llvm.org/D71732
This is a purely cosmetic change that is NFC in terms of the binary
output. I bugs me that I called the attribute DW_AT_LLVM_isysroot
since the "i" is an artifact of GCC command line option syntax
(-isysroot is in the category of -i options) and doesn't carry any
useful information otherwise.
This attribute only appears in Clang module debug info.

Since OCaml 4.02 (released in 2014), strings and bytes are different
types, but up until OCaml 4.06, the compiler defaulted to a
compatibility mode "unsafe-string". OCaml 4.06 flips the default to
"safe-string", breaking the test.
This change should be compatible with OCaml 4.02+, but is only truly
necessary for OCaml 4.06+.

This patch redefines freeze instruction from being UnaryOperator to a subclass of UnaryInstruction.
ConstantExpr freeze is removed, as discussed in the previous review.
FreezeOperator is not added because there's no ConstantExpr freeze.
`freeze i8* null` test is added to `test/Bindings/llvm-c/freeze.ll` as well, because the null pointer-related bug in `tools/llvm-c/echo.cpp` is now fixed.
InstVisitor has visitFreeze now because freeze is not unaryop anymore.

The motivation for this is to be able to see `musttail` for languages that require mandatory tail calls for correctness. Today only the weaker `LLVMSetTail` is exposed and there is no way to set `GuaranteedTailCallOpt` via the C API.
