Generalize the existing eq/ne case using `extractParts`. The original code only
handled narrowings for types of width 2n->n. This generalization allows for any
type that can be broken down by `extractParts`.
General overview is:
- Loop over each narrow-sized part and do exactly what the 2-register case did.
- Loop over the leftover-sized parts and do the same thing
- Widen the leftover-sized XOR results to the desired narrow size
- OR that all together and then do the comparison against 0 (just like the old
code)
This shows up a lot when building clang for AArch64 using GlobalISel, so it's
worth fixing. For the sake of simplicity, this doesn't handle the non-eq/ne
case yet.
Also remove the code in this case that notifies the observer; we're just going
to delete MI anyway so talking to the observer shouldn't be necessary.

Summary: This patch is a part of an attempt to obtain more
timer data from the analyzer. In this patch, we try to use
LLVM::TimeRecord to save time before starting the analysis
and to print the time that a specific function takes while
getting analyzed.
The timer data is printed along with the
-analyzer-display-progress outputs.

This call would incorrectly overwrite (with the .debug_rnglists.dwo from
the executable, if there was one) the rnglists section instead of the
correct value (from the .debug_rnglists.dwo in the .dwo file) that's
applied in DWARFUnit::tryExtractDIEsIfNeeded
Integral AND and OR follow the simple conjunction and disjuction rules
for lattice building. This revision also completes some of the Merge
refactoring by moving the remainder parts that are merger specific from
sparsification into utils files.

For Clang, `MCUseDwarfDirectory` is true by default for the majority cases
(-fintegrated-as or -gdwarf-5; most targets use -fintegrated-as by default).
Defaulting MCUseDwarfDirectory to true can reduce the differences between clang
and llc.

It turns out that COMPILER_RT_TEST_COMPILER_CFLAGS is actually a string
that is being appended to and not a list.
Therefore, append the thread-safety flags to the string. Because CMake
separates list elements by ';' when turning into a string, also
substitute ';' with ' '.

While GNU as only allows the directory form of the .file directive for DWARF v5,
the integrated assembler prefers the directory form on all DWARF versions
(-fdwarf-directory-asm).
We currently set CC1 -fno-dwarf-directory-asm for -fno-integrated-as -gdwarf-5
which may cause the directory entry 0 and the filename entry 0 to be incorrect
(see D105662 and the example below). This patch makes -fno-integrated-as -gdwarf-5 use
-fdwarf-directory-asm as well.
```
cd /tmp/c

Right now, we only accept x/c with nonzero c, since this

FP and INT as far as lattice computations go. The codegen
keeps the division though to preserve precise semantics.

This reverts commit 82a38837150099288a1262391ef43e1fd69ffde4.
The original version had a copy-paste error: using the Interrupt timeout
for the ResumeSynchronous wait, which is clearly wrong. This error would
have been evident with real use, but the interrupt is long enough that it
only caused one testsuite failure (in the Swift fork).
Anyway, I found that mistake and fixed it and checked all the other places
where I had to plumb through a timeout, and added a test with a short
interrupt timeout stepping over a function that takes 3x the interrupt timeout
to complete, so that should detect a similar mistake in the future.
An assertion of the following can occur because Altivec and VSX splats use a different operand number for the immediate:
```
int64_t llvm::MachineOperand::getImm() const: Assertion `isImm() && "Wrong MachineOperand accessor"' failed.
```
This patch updates PPCMIPeephole.cpp assign the correct splat immediate.

This is a fix of https://reviews.llvm.org/D104956, which broke the gcc5 build.
We opt to use unit tests rather than check tests as the lattice/merger code is a small C++ component with a well-defined API. Testing this API via check tests would be far less direct and readable. In addition, as the check tests will only be able to test the API indirectly, the tests may break based on unrelated changes; e.g. changes in linalg.

Continuing from D105763, this allows placing certain properties
about attributes in the TableGen definition. In particular, we
store whether an attribute applies to fn/param/ret (or a combination
thereof). This information is used by the Verifier, as well as the
ForceFunctionAttrs pass. I also plan to use this in LLParser,
which also duplicates info on which attributes are valid where.
This keeps metadata about attributes in one place, and makes it
more likely that it stays in sync, rather than in various
functions spread across the codebase.

This is now the same as isIntAttrKind(), so use that instead, as
it does not require manual maintenance. The naming is also more
accurate in that both int and type attributes have an argument,
but this method was only targeting int attributes.
I initially wanted to tighten the AttrBuilder assertion, but we
have some in-tree uses that would violate it.
Update (mainly) vXf32/vXf64 -> vXi8/vXi16 fptosi/fptoui costs based on the worst case costs from the script in D103695.
Move to using legalized types wherever possible, which allows us to prune the cost tables.
This change is a step towards implementing codegen for __builtin_clz().
Full support for CLZ with a regression test will follow shortly.
