By iterating backwards over the globs we can exit the loop as soon as we find a match.
While we're here:
- Regex doesn't need to be mutable.
- We can reserve the amount of Globs needed ahead of time.
- Using a SmallVector with size 0 is slightly more space efficient than a std::vector.

It seems that TestErrorMessages.test is failing on the standalone + Xcode builds
as lldb-server executable can't be found by lit's default PATH search. I assume
invoking lldb-server via a lit substitution gets this working again as
everything else is working, so that's what this patch is doing.
I had to add the lldb-server substitution as the test seems lldb-server specific
and we don't want it to default to debugserver on Darwin.
Using a substitution also seems in general like a good idea so that the commands
lit is printing on failure are using the full path to lldb-server and can be
re-run in a terminal.

This is the last step in removing cost-kind as a consideration in the basic class model for intrinsics.
See D89461 for the start of that.
Subsequent commits dealt with each of the special-case intrinsics that had customization here in the
basic class. This should remove a barrier to retrying
D87188 (canonicalization to the abs intrinsic).
The ARM and x86 cost diffs seen here may be wrong because the target-specific overrides have their own
bugs, but we hope this is less wrong - if something has a significant throughput cost, then it should
have a significant size / blended cost too by default.
The only behavioral diff in current regression tests is shown in the x86 scatter-gather test (which is
misplaced or broken because it runs the entire -O3 pipeline) - we unrolled less, and we assume that is
a improvement.

Explicitly copy dbregs to new threads to ensure that watchpoints
are propagated properly. Fixes the test failure due to apparent kernel
race between reporting a new thread and resuming main thread execution
that makes implicit inheritance of dbregs unreliable. By copying them
explicitly, we ensure that the new thread correctly respects watchpoints
that were set after the thread was created but before it was reported.
The code is copied from the NetBSD plugin and modernized to use
llvm::Error.

Some use cases (e.g. kernel devs) have strict requirements to only enable
features available with -march=armv8-a, e.g. no armv8.1-a. Enabling RAS 1.1 in
all AArch64 means they can consider to support it.
Bear in mind that the first versions of the Armv8 architecture still do not
support RAS 1.1. This patch only lets devs write code with the user-friendly
register mnemonic instead of the ugly generic S<op0>_<op1>_<Cn>_<Cm>_<op2>.
They still need to place runtime checks to make sure that the CPU to run on
supports RAS 1.1.

Part 2 of a fix for JITed code debugging. This has been a regression from 5.0 to 6.0 and it's still reproducible on current master: https://bugs.llvm.org/show_bug.cgi?id=36209 Part 1 was D61611 a while ago.
The in-memory object files we obtain from JITLoaderGDB are not yet relocated. It looks like this used to happen on the LLDB side and my guess is that it broke with D38142. (However, it's hard to tell because the whole thing was broken already due to the bug in part 1.) The patch moved relocation resolution to a later point in time and didn't apply it to in-memory objects. I am not aware of any reason why we wouldn't resolve relocations per-se, so I made it unconditional here. On Debian, it fixes the bug for me and all tests in `check-lldb` are still fine.

Slicing, that is element access with `[being🔚step]` structure, is
a common Python idiom for sequence-like containers. It is also necessary
to support custom accessor for operations with variadic operands and
results (an operation an return a slice of its operands that correspond
to the given variadic group).
Add generic utility to support slicing in Python bindings and use it
for operation operands and results.

We plan to eliminate error-prone and obsolete Clang-Rename API from Clangd. To
do that, we will introduce Decl canonicalization rules that will make renaming
code simpler and easier to maintain (D71880).
To ensure smooth transition to the new implementation, many Clang-Rename tests
will be adopted in Clangd to prevent any possible regressions. This patch is
the first in the chain of test migration patches. It improves existing tests
and adopts tests from Clang-Rename's alias, class and enum testing files.
