A previous attempt to cleanup module imports broke installing via
pip/setup.py [1]. This should be fixed now.

This minor refactoring allows reducing the amount of processing that
is duplicated when we re-run a flaky test. It also has the nice
side effect that libc++'s current test format supports flaky .sh.cpp
tests, because those are built on top of _runShTest, not executeShTest.
This allows defining substitutions in terms of other substitutions. For
example, a %build substitution could be defined in terms of a %cxx
substitution as '%cxx %s -o %t.exe' and the script would be properly
expanded.

Summary:
Some compressed instructions match against negative values; store
immediates as a signed value such that these patterns will now match
the intended instructions.

Follow-up of D72172 and D72180
This patch passes `uint64_t Address` to print methods of PC-relative
operands so that subsequent target specific patches can change
`*InstPrinter::print{Operand,PCRelImm,...}` to customize the output.
Add MCInstPrinter::PrintBranchImmAsAddress which is set to true by
llvm-objdump.
```
// Current llvm-objdump -d output
aarch64: 20000: bl #0
ppc: 20000: bl .+4
x86: 20000: callq 0
// Ideal output
aarch64: 20000: bl 0x20000
ppc: 20000: bl 0x20004
x86: 20000: callq 0x20005
// GNU objdump -d. The lack of 0x is not ideal because the result cannot be re-assembled
aarch64: 20000: bl 20000
ppc: 20000: bl 0x20004
x86: 20000: callq 20005
```
In `lib/Target/X86/X86GenAsmWriter1.inc` (generated by `llvm-tblgen -gen-asm-writer`):
```
case 12:
// CALL64pcrel32, CALLpcrel16, CALLpcrel32, EH_SjLj_Setup, JCXZ, JECXZ, J...
- printPCRelImm(MI, 0, O);
+ printPCRelImm(MI, Address, 0, O);
return;
```
Some targets have 2 `printOperand` overloads, one without `Address` and
one with `Address`. They should annotate derived `Operand` properly with
`let OperandType = "OPERAND_PCREL"`.

This allows creating custom test formats on top of `executeShTest` that
inject commands at the beginning of the file being parsed, without
requiring these commands to physically appear in the test file itself.
For example, one could define a test format that prints out additional
debug information at the beginning of each test. More realistically,
this has been used to define custom test formats like one that supports
compilation failure tests (e.g. with the extension `compile.fail.cpp`)
by injecting a command that calls the compiler on the file itself and
expects it to fail.
Without this change, the only alternative is to create a temporary file
with the same content as the original test, then prepend the desired
`// RUN:` lines to that file, and call `executeShTest` on that file
instead. This is both slow and cumbersome to do.

Remove the local versions of the IR_FUNCTION_RE matcher (they weren't doing anything different), and ensure all the function name matchers accept '.' and '-'.
We don't need to use '\.' inside python regex sets either, or '\-' as long as thats at the end of the set.
For MTE error reporting we will need to expose interfaces for crash handlers
to use to interpret scudo headers and metadata. The intent is that these
interfaces will live in scudo/interface.h.
Move the existing interface.h into an include/scudo directory and make it
independent of the internal headers, so that we will be able to add the
interfaces there.

This reverts commit e9f22fd429.
When building with -DLLVM_USE_SANITIZER="Thread", check-llvm has 70
failing tests with this revision, and 29 without this revision.
This commit adds a new keyword in lit called ALLOW_RETRIES. This keyword
takes a single integer as an argument, and it allows the test to fail that
number of times before it first succeeds.
This work attempts to make the existing test_retry_attempts more flexible
by allowing by-test customization, as well as eliminate libc++'s FLAKY_TEST
custom logic.

This patch generates TableGen descriptions for the specified register
banks which contain a list of register sizes corresponding to the
available HwModes. The appropriate size is used during codegen according
to the current HwMode. As this HwMode was not available on generation,
it is set upon construction of the RegisterBankInfo class. Targets
simply need to provide the HwMode argument to the
<target>GenRegisterBankInfo constructor.
The RISC-V RegisterBankInfo constructor has been updated accordingly
(plus an unused argument removed).

This patch rewrites the RegisterBankEmitter class to derive
RegisterClassHierarchy from CodeGenTarget::getRegBank() rather than
constructing our own copy. All are now accessed through a const
reference.
