Pass EvalCallOptions via runCheckersForEvalCall into defaultEvalCall.

This patch takes the IO redirection logic from ScriptInterpreterPython
and moves it into the interpreter library so that it can be used by
other script interpreters. I've turned it into a RAII object so that we
don't have to worry about cleaning up in the calling code.

Cleanup MemoryDependenceAnalysis.h as well - GVN.h was also implicitly including AliasAnalysis.h via this.
Fix implicit include dependencies in source files and replace legacy AliasAnalysis typedef with AAResults where necessary.
Summary:
This somewhat matches the --aa-pipeline option, which separates out any
AA analyses to make sure they run before other passes.
Makes check-llvm failures under new PM go from 2356 -> 2303.
AA passes are not handled by PassBuilder::parsePassPipeline() but rather
PassBuilder::parseAAPipeline(), which is why this fixes some failures.

This change enables PowerPC compiler builtins to generate constrained
floating point operations when clang is indicated to do so.
A couple of possibly unexpected backend divergences between constrained
floating point and regular behavior are highlighted under the test tag
FIXME-CHECK. This may be something for those on the PPC backend to look
at.

fabs(X) * fabs(Y) --> fabs(X * Y)
fabs(X) / fabs(Y) --> fabs(X / Y)
If both operands of fmul/fdiv are positive, then the result must be positive.
There's a NAN corner-case that prevents removing the more specific fold just
above this one:
fabs(X) * fabs(X) -> X * X
That fold works even with NAN because the sign-bit result of the multiply is
not specified if X is NAN.
We can't remove that and use the more general fold that is proposed here
because once we convert to this:
fabs (X * X)
...it is not legal to simplify the 'fabs' out of that expression when X is NAN.
That's because fabs() guarantees that the sign-bit is always cleared - even
for NAN values.
So this patch has the potential to lose information, but it seems unlikely if
we do the more specific fold ahead of this one.

This adds code to lower f32 to f16 fp_trunc's using a pair of MVE VCVT
instructions. Due to v4f16 not being legal, fp_round are often split up
fairly early. So this reconstructs the vcvt's from a buildvector of
fp_rounds from two vector inputs. Something like:
BUILDVECTOR(FP_ROUND(EXTRACT_ELT(X, 0),
FP_ROUND(EXTRACT_ELT(Y, 0),
FP_ROUND(EXTRACT_ELT(X, 1),
FP_ROUND(EXTRACT_ELT(Y, 1), ...)
It adds a VCVTN node to handle this, which like VMOVN or VQMOVN lowers
into the top/bottom lanes of an MVE instruction.

Summary:
LDRAA and LDRAB in their writeback variant should softfail when the same
register is used as result and base.
This patch adds a custom decoder that catches such case and emits a
warning when it occurs.

Give up folding an expression if the fragment of one of the operands
would require laying out a fragment already being laid out. This
prevents hitting an infinite recursion when a fill size expression
refers to a later fragment since computing the offset of that fragment
would require laying out the fill fragment and thus computing its size
expression.

This function was modifying and returning pointers to static storage,
which meant that any two accesses to different Scalar objects could
potentially race (depending on which types the objects were storing and
the host endianness).
In the new version the user is responsible for providing a buffer into
which this method will store its binary representation. The main caller
(RegisterValue::GetBytes) already has one such buffer handy, so this did
not require any major rewrites.
To make that work, I've needed to mark the RegisterValue value buffer
mutable -- not an ideal solution, but definitely better than modifying
global storage. This could be further improved by changing
RegisterValue::GetBytes to take a buffer too.
The main interface has been migrated to Align already but a few backends where broadening the type from Align to MaybeAlign.
This patch makes sure all implementations conform to the public API.

This file has grown quite large and could do with being split up. This
splits away the load/store + cast tests into a separate file. Some
masked load/store + cast tests have been added too, along with some
extra load/store + fpcast tests.
There is no reason to report an error in `printSectionHeaders()`, we can report
a warning and continue dumping. This is what the patch does.
Differential revision: https://reviews.llvm.org/D82462
In the process of running this check on a large codebase I found a
number of limitations, and thought I would pass on my fixes for
possible integration upstream:
* Templated function call operators are not supported
* Function object constructors are always used directly in the lambda
body, even if their arguments are not captured
* Placeholders with namespace qualifiers (std::placeholders::_1) are
not detected
* Lambda arguments should be forwarded to the stored function
* Data members from other classes still get captured with this
* Expressions (as opposed to variables) inside std::ref are not captured
properly
* Function object templates sometimes have their template arguments
replaced with concrete types
This patch resolves all those issues and adds suitable unit tests.
Summary:
NOTE: There is a mailing list discussion on this: http://lists.llvm.org/pipermail/llvm-dev/2019-December/137632.html
Complemantary to the assumption outliner prototype in D71692, this patch
shows how we could simplify the code emitted for an alignemnt
assumption. The generated code is smaller, less fragile, and it makes it
easier to recognize the additional use as a "assumption use".
As mentioned in D71692 and on the mailing list, we could adopt this
scheme, and similar schemes for other patterns, without adopting the
assumption outlining.
