Nikita Popov 11950efe06 [ConstExpr] Remove div/rem constant expressions
D128820 stopped creating div/rem constant expressions by default;
this patch removes support for them entirely.

The getUDiv(), getExactUDiv(), getSDiv(), getExactSDiv(), getURem()
and getSRem() on ConstantExpr are removed, and ConstantExpr::get()
now only accepts binary operators for which
ConstantExpr::isSupportedBinOp() returns true. Uses of these methods
may be replaced either by corresponding IRBuilder methods, or
ConstantFoldBinaryOpOperands (if a constant result is required).

On the C API side, LLVMConstUDiv, LLVMConstExactUDiv, LLVMConstSDiv,
LLVMConstExactSDiv, LLVMConstURem and LLVMConstSRem are removed and
corresponding LLVMBuild methods should be used.

Importantly, this also means that constant expressions can no longer
trap! This patch still keeps the canTrap() method to minimize diff --
I plan to drop it in a separate NFC patch.

Nikita Popov 41d5033eb1 [IR] Enable opaque pointers by default
This enabled opaque pointers by default in LLVM. The effect of this
is twofold:

* If IR that contains *neither* explicit ptr nor %T* types is passed
  to tools, we will now use opaque pointer mode, unless
  -opaque-pointers=0 has been explicitly passed.
* Users of LLVM as a library will now default to opaque pointers.
  It is possible to opt-out by calling setOpaquePointers(false) on
  LLVMContext.

A cmake option to toggle this default will not be provided. Frontends
or other tools that want to (temporarily) keep using typed pointers
should disable opaque pointers via LLVMContext.

Nicolas Abram Lujan 436bbce765 [llvm-c] Add functions for enabling and creating opaque pointers
This is based on https://reviews.llvm.org/D125168 which adds a
wrapper to allow use of opaque pointers from the C API.

I added an opaque pointer mode test to echo.ll, and to fix assertions
that forbid the use of mixed typed and opaque pointers that were
triggering in it I had to also add wrappers for setOpaquePointers()
and isOpaquePointer().

I also changed echo.ll to remove a bitcast i32* %x to i8*, because
passing it through llvm-as and llvm-dis was generating a
%0 = bitcast ptr %x to ptr, but when building that same bitcast in
echo.cpp it was getting elided by IRBuilderBase::CreateCast
(08ac661248/llvm/include/llvm/IR/IRBuilder.h (L1998-L1999)).

David Candler b8baa2a913 [ARM][AArch64] Require appropriate features for crypto algorithms
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.

Craig Disselkoen 51cad041e0 C API: functions to get mask of a ShuffleVector
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.

Mircea Trofin 70f8d0ac8a [llvm] Development-mode InlineAdvisor
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.

This addresses point 1 of PR44213.
https://bugs.llvm.org/show_bug.cgi?id=44213

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.
