[X86] Add test case to show missed opportunity to remove an explicit AND on the bit position from BT when it has known zeros. NFC

If the bit position has known zeros in it, then the AND immediate will likely be optimized to remove bits.

This can prevent GetDemandedBits from recognizing that the AND is unnecessary.

This test was failing in one of our setups because the generated ModuleID

This should have been part of r354490.

llvm-svn: 354493

Summary:
Following on from the review for D58088, this patch provides the
prerequisite to_address() implementation that's needed to have
pointer_iterator support unique_ptr.

The late bound return should be removed once we move to C++14 to better
align with the C++20 declaration. Also, this implementation can be removed
once we move to C++20 where it's defined as std::to_addres()

The std::pointer_traits<>::to_address(p) variations of these overloads has
not been implemented.

Every cycle, the Scheduler checks if instructions in the ReadySet can be issued
to the underlying pipelines. If an instruction cannot be issued because one or
more pipeline resources are unavailable, then field
Instruction::CriticalResourceMask is updated with the resource identifier of the
unavailable resources.

If an instruction cannot be promoted from the PendingSet to the ReadySet because
of a memory dependency, then field Instruction::CriticalMemDep is updated with
the identifier of the dependending memory instruction.

Bottleneck information is collected after every cycle for instructions that are
waiting to execute. The idea is to help identify causes of bottlenecks; this
information can be used in future to implement a bottleneck analysis.

A number of the obj2yaml tests end in .yaml, but .yaml is not a default
file type picked up by lit, so these tests weren't being run when
running the testsuite as a whole (they could be run explicitly still).
This change adds a lit local config file to specify the known file types
for obj2yaml tests (.yaml and .test). Additionally, it fixes the
yaml2obj config file to allow both .test and .yaml suffixed tests
(previously, the two tests ending in '.test' were not being run).

Summary:
This patch adds a more sophisticated team reduction scheme to the OpenMP libomptarget-nvptx runtime.

The scheme uses a fixed size global memory buffer whose length can be adjusted via compiler flag:
```
-fopenmp-cuda-teams-reduction-recs-num=1024
```
The global buffer is a structure of arrays (with default size of 1024 each and controlled by the above flag), one array for each reduction variable.

Values in the buffer are processed by the last team to finish executing the body of the target region.

In addition to adding support for the new flag, the compiler also emits special functions used for the reduction of the intermediate reduction values. These changes will be added in a separate compiler patch following this one.

This patch adds a lookup table to speed up resource queries in the ResourceManager.
This patch also moves helper function 'getResourceStateIndex()' from
ResourceManager.cpp to Support.h, so that we can reuse that logic in the

Three MIPS-specific sections `.reginfo`, `.MIPS.options`, and `.MIPS.abiflags`
are used by loader to read their contents and setup environment for running
a program. Loader looks up these data in the corresponding segments:
`PT_MIPS_REGINFO`, `PT_MIPS_OPTIONS`, and `PT_MIPS_ABIFLAGS` respectively.

This patch put these sections to separate segments like we do already
for ARM `SHT_ARM_EXIDX` section.

Split the recognition into NetBSD executables & shared libraries
and core(5) files.

Introduce new owner type: "NetBSD-CORE", as core(5) files are not tagged
in the same way as regular NetBSD executables.

Stop using incorrectly ABI_TAG and ABI_SIZE.  Introduce IDENT_TAG,
IDENT_DECSZ, IDENT_NAMESZ and PROCINFO.

The new values detect correctly the NetBSD images.

The patch has been originally written by Kamil Rytarowski.  I've added
tests and applied minor code changes per review.  The work has been
sponsored by the NetBSD Foundation.
