Summary:
-simplifycfg is the legacy pass name for SimplifyCFGPass.
There is already -simplify-cfg in FUNCTION_PASS_WITH_PARAMS which
handles options for SimplifyCFGPass. Maybe that should be renamed to
-simplifycfg as well?
This reduces the number of check-llvm failures under NewPM from 2619 to 2392.

Summary:
Currently, add_llvm_library would create an OBJECT library alongside
of a STATIC / SHARED library, but losing the link interface (its
elements would become dependencies instead). To support scenarios
where linking an object library also brings in its usage
requirements, this patch adds support for 'stand-alone' OBJECT
libraries - i.e. without an accompanying SHARED/STATIC library, and
maintaining the link interface defined by the user.
This is useful for cases where, for example, we want to build a part
of a component separately. Using a STATIC target would incur the risk
that symbols not referenced in the consumer would be dropped (which may
be undesirable).
The current application is the ML part of Analysis. It should be part
of the Analysis component, so it may reference other analyses; and (in
upcoming changes) it has dependencies on optional libraries.

Soon it will be disallowed to depend on MachineFunction state in the
constructor. This was only being used to get the MachineRegisterInfo
for an assert, which I'm not sure is necessarily worth it. I would
think any missing defs would be caught by the verifier later instead.
Summary: We are missing the error-bit somehow if the error-bit is propagated
through the code path: "error type/expr" -> "template argument" ->
"template specialization type", which will lead to crashes.

The "type" argument to the function is mostly useless -- the only
interesting aspect of it is signedness. Pass signedness directly and
compute the value of bits and signedness fields -- that's exactly
what the single caller of this function does.
Summary:
The SIModeRegister pass attempts to generate the minimal number of
writes to the mode register. However it was failing to correctly
deal with some loops, resulting in some redundant setreg instructions
being inserted.
This change amends the pass to avoid generating these redundant
instructions.

This patch add support for eliminating MemoryDefs that do not have any
aliasing users, which indicates that there are no reads/writes to the
memory location until the end of the function.
To eliminate such defs, we have to ensure that the underlying object is
not visible in the caller and does not escape via returning. We need a
separate check for that, as InvisibleToCaller does not consider returns.

Summary:
After D50078, we're experiencing unexpected un-indent using a style combining `AlignOperands: DontAlign` with `BreakBeforeTernaryOperators: false`, such as Google's JavaScript style:
```
% bin/clang-format -style=google ~/test.js
aaaaaaaaaaa = bbbbbbbb ? cccccccccccccccccc() :
dddddddddd ? eeeeeeeeeeeeee :
fffff;
```
The issue lies with the interaction of `AlignOperands: DontAlign` and the edited code section in ContinuationIndenter.cpp, which de-dents the intent by `Style.ContinuationIndentWidth`. From [[ ac3e5c4d93/clang/include/clang/Format/Format.h (L170) | the documentation ]] of AlignOperands: DontAlign:
> The wrapped lines are indented `ContinuationIndentWidth` spaces from the start of the line.
So the de-dent effectively erases the necessary `ContinuationIndentWidth` in that case.
This patch restores the `AlignOperands: DontAlign` behavior, producing:
```
% bin/clang-format -style=google ~/test.js
aaaaaaaaaaa = bbbbbbbb ? cccccccccccccccccc() :
dddddddddd ? eeeeeeeeeeeeee :
fffff;

Summary:
Whenever Neon is not supported, a generic message is printed:
error: "NEON support not enabled"
Followed by a series of other error messages that are not useful once
the first one is printed.
This patch gives a more precise message in the case where Neon is
unsupported because an invalid float ABI was specified: the soft float
ABI.
error: "NEON intrinsics not available with the soft-float ABI. Please
use -mfloat-abi=softfp or -mfloat-abi=hard"
This message is the same one that GCC gives, so it is also making their
diagnostics more compatible with each other.
Also, by rearranging preprocessor directives, these "unsupported" error
messages are now the only ones printed out, which is also GCC's
behaviour.

Summary:
This change permits scalar bfloats to be loaded, stored, moved and
used as function call arguments and return values, whenever the bf16
feature is supported by the subtarget.
Previously that was only supported in the presence of the fullfp16
feature, because the code generation strategy depended on instructions
from that extension. This change adds alternative code generation
strategies so that those operations can be done even without fullfp16.
The strategy for loads and stores is to replace VLDRH/VSTRH with
integer LDRH/STRH plus a move between register classes. I've written
isel patterns for those, conditional on //not// having the fullfp16
feature (so that in the fullfp16 case, the existing patterns will
still be used).
For function arguments and returns, instead of writing isel patterns
to match `VMOVhr` and `VMOVrh`, I've avoided generating those SDNodes
in the first place, by factoring out the code that constructs them
into helper functions `MoveToHPR` and `MoveFromHPR` which have a
fallback for non-fullfp16 subtargets.
The current output code is not especially pretty: in the new test file
you can see unnecessary store/load pairs implementing no-op bitcasts,
and lots of pointless moves back and forth between FP registers and
GPRs. But it at least works, which is an improvement on the previous
situation.

Eric Christopher informed me that FastISel memcpy handling creates

better to be defensive here.
