Refactor getHostCPUName to allow testing on non-native hardware.
This refactors getHostCPUName so that for the architectures that get the
host cpu info on linux from /proc/cpuinfo, the /proc/cpuinfo parsing
logic is present in the build, even if it wasn't built on a linux system
for that architecture.
Since the code is present in the build, we can then test that code also
on other systems, i.e. we don't need to have buildbots setup for all
architectures on linux to be able to test this. Instead, developers will
test this as part of the regression test run.
As an example, a few unit tests are added to test getHostCPUName for ARM
running linux. A unit test is preferred over a lit-based test, since the
expectation is that in the future, the functionality here will grow over
what can be tested with "llc -mcpu=native".
This is a preparation step to enable implementing the range of
improvements discussed on PR30516, such as adding AArch64 support,
support for big.LITTLE systems, reducing code duplication.

[APInt] Remove references to integerPartWidth outside of APFloat implentation.
Turns out integerPartWidth only explicitly defines the width of the tc functions in the APInt class. Functions that aren't used by APInt implementation itself. Many places in the code base already assume APInt is made up of 64-bit pieces. Explicitly assuming 64-bit here doesn't make that situation much worse.

Some of the GEP combines (e.g., descaling) can't handle vector GEPs. We have an

pointers if at least one of its operands is vector-typed (e.g., its pointer
operand could be a scalar, but its index could be a vector). We should just
check the type of the GEP itself. This should fix PR32414.

This is less important than increase threshold for private memory,

Unrolling more for local memory serves three purposes: it allows
to combine ds operations if offset becomes static, saves registers
used for offsets in case of static offsets, and allows better lds

[AVX-512] Fix accidental uses of AH/BH/CH/DH after copies to/from mask registers
We've had several bugs(PR32256, PR32241) recently that resulted from usages of AH/BH/CH/DH either before or after a copy to/from a mask register.
This ultimately occurs because we create COPY_TO_REGCLASS with VK1 and GR8. Then in CopyToFromAsymmetricReg in X86InstrInfo we find a 32-bit super register for the GR8 to emit the KMOV with. But as these tests are demonstrating, its possible for the GR8 register to be a high register and we end up doing an accidental extra or insert from bits 15:8.
I think the best way forward is to stop making copies directly between mask registers and GR8/GR16. Instead I think we should restrict to only copies between mask registers and GR32/GR64 and use EXTRACT_SUBREG/INSERT_SUBREG to handle the conversion from GR32 to GR16/8 or vice versa.
Unfortunately, this complicates fastisel a bit more now to create the subreg extracts where we used to create GR8 copies. We can probably make a helper function to bring down the repitition.
This does result in KMOVD being used for copies when BWI is available because we don't know the original mask register size. This caused a lot of deltas on tests because we have to split the checks for KMOVD vs KMOVW based on BWI.

Add the error handling for Mach-O dyld compact lazy bind, weak bind and
rebase entry errors and test cases for each of the error checks.
Also verified with Nick Kledzik that a BIND_OPCODE_SET_ADDEND_SLEB
opcode is legal in a lazy bind table, so code that had that as an error
check was removed.
With MachORebaseEntry and MachOBindEntry classes now returning
an llvm::Error in all cases for malformed input the variables Malformed
and logic to set use them is no longer needed and has been removed
from those classes.
Also in a few places, removed the redundant Done assignment to true
when also calling moveToEnd() as it does that assignment.
This only leaves the dyld compact export entries left to have
error handling yet to be added for the dyld compact info.

[LV] Transform truncations of non-primary induction variables
The vectorizer tries to replace truncations of induction variables with new
induction variables having the smaller type. After r295063, this optimization
was applied to all integer induction variables, including non-primary ones.
When optimizing the truncation of a non-primary induction variable, we still
need to transform the new induction so that it has the correct start value.
This should fix PR32419.

[APInt] Move operator=(uint64_t) inline as its pretty simple and is often used with small constants that the compiler can optimize.
While there recognize that we only need to clearUnusedBits on the single word case.

[TableGen] Print #nnn as a name of an non-native reg unit with id nnn
When using -debug with -gen-register-info, tablegen will crash when
trying to print a name of a non-native register unit. This patch only
affects the debug information generated while running llvm-tblgen,
and has no impact on the compilable code coming out of it.

[Support] Avoid concurrency hazard in signal handler registration
Several static functions from the signal API can be invoked
simultaneously; RemoveFileOnSignal for instance can be called indirectly
by multiple parallel loadModule() invocations, which might lead to
the assertion:
Assertion failed: (NumRegisteredSignals < array_lengthof(RegisteredSignalInfo) && "Out of space for signal handlers!"),
function RegisterHandler, file /llvm/lib/Support/Unix/Signals.inc, line 105.
RemoveFileOnSignal calls RegisterHandlers(), which isn't currently
mutex protected, leading to the behavior above. This potentially affect
a few other users of RegisterHandlers() too.

[APInt] Move operator&=(uint64_t) inline and use memset to clear the upper words.
This method is pretty new and probably isn't use much in the code base so this should have a negligible size impact. The OR and XOR operators are already inline.
