This reverts commit 1ec6e1eb.

This change causes a significant compile-time regression:
https://llvm-compile-time-tracker.com/compare.php?from=dd0b8b94d0796bd895cc998dd163b4fbebceb0b8&to=1ec6e1eb8a084bffae8a40236eb9925d8026dd07&stat=instructions

I assume that this is due to the non-NFC part of the change, which
now performs expensive nowrap inference even for nowrap flags that
are not used by the particular code.

In an effort to make code around flag determination more readable, and (possibly) prepare for a follow up change, factor out some of the flag detection logic.  In the process, reduce the number of locations we mutate wrap flags by a couple.

Note that this isn't NFC.  The old code tried for NSW xor (NUW || NW).  This is, two different paths computed different sets of wrap flags.  The new code will try for all three.  The result is that some expressions end up with a few extra flags set.

This is used to test RemoveRedundantDbgInstrs(), which is used by other
passes.

This reverts the revert commit c8d73d93.

It includes a fix for cases where we missed inserting VPValues
for some selects, which should fix PR48142.

Also follows what we do in std ops too and move it before :.

9218ff50 removed the BUILD.txt file, and as a subtle side-effect
libLLVMFrontendOpenACC wasn't a dependency of `ninja check` anymore.
However llvm-config requires all components to be built, and the
relevant test is broken when libLLVMFrontendOpenACC isn't built.

Unittest for libLLVMFrontendOpenACC are pending, but this addition
should fix some bots in the meantime.

We're dropping a common offset from both GEPs here. It's not
necessary for the access sizes to be the same as well.

Differential Revision: https://reviews.llvm.org/D91388

This was changed recently with D90554 / f7eac51b
...because we had a regression testing blindspot for intrinsics
that are expected to be lowered to libcalls.

In general, we want the *size* cost for a scalar call to be cheap
even if the other costs are expensive - we expect it to just be
a branch with some optional stack manipulation.

It is likely that we will want to carve out some
exceptions/overrides to this rule as follow-up patches for
calls that have some general and/or target-specific difference
to the expected lowering.

This was noticed as a regression in unrolling, so we have a test
for that now along with a couple of direct cost model tests.

If the assumed scalarization costs for the oversized vector
calls are not realistic, that would be another follow-up
refinement of the cost models.

This simplifies the code the allocator has to executed

CUDA header files may contain CUDA specific code
that is why they have special extension, which
can be recognized by nvcc (CUDA compiler driver)
as CUDA source file.

the implementation is known-broken for certain inputs,
the bugreport was up for a significant amount of timer,
and there has been no activity to address it.
Therefore, just completely rip out all of misexpect handling.

I suspect, fixing it requires redesigning the internals of MD_misexpect.
Should anyone commit to fixing the implementation problem,
starting from clean slate may be better anyways.

This reverts commit 7bdad084,
