cg_llvm: Clean up FFI calls for operand bundles

All of these FFI functions have equivalents in the stable LLVM-C API, though `LLVMBuildCallBr` requires a temporary polyfill on LLVM 18.

This PR also creates a clear split between `OperandBundleOwned` and `OperandBundle`, and updates the internals of the owner to be a little less terrifying.

Rollup merge of #132319 - Zalathar:add-module-flag, r=jieyouxu 
cg_llvm: Clean up FFI calls for setting module flags

This is a combination of several inter-related changes to how module flags are set:

- Remove some unnecessary code for setting an `"LTOPostLink"` flag, which has been obsolete since LLVM 17.
- Define our own enum instead of relying on enum values defined by LLVM's unstable C++ API.
- Use safe wrapper functions to set module flags, instead of direct `unsafe` calls.
- Consistently pass pointer/length strings instead of C strings.
- Remove or shrink some `unsafe` blocks.

ba81dbf3c6 Don't set unnecessary module flag "LTOPostLink" 
This module flag was an internal detail of LLVM's optimization passes, and all
code involving it was removed in LLVM 17.

Rollup merge of #131956 - Zalathar:llvm-counters, r=compiler-errors,Swatinem 
coverage: Pass coverage mappings to LLVM as separate structs

Instead of trying to cram *N* different kinds of coverage mapping data into a single list for FFI, pass *N* different lists of simpler structs.

This avoids the need to fill unused fields with dummy values, and avoids the need to tag structs with their underlying kind. It also lets us call the dedicated LLVM constructors for each different mapping type, instead of having to go through the complex general-purpose constructor.

Even though this adds multiple new structs to the FFI surface area, the resulting C++ code is simpler and shorter.

---

I've structured this mostly as a single atomic patch, rather than a series of incremental changes, because that avoids the need to make fiddly fixes to code that is about to be deleted anyway.

eaaa94318b Unpin cc and upgrade to the latest version 
`cc` was previously pinned because version 1.1.106 dropped support for
Visual Studio 12 (2013), and we wanted to decouple that from the rest of
the automated updates. As noted in [2], there is no longer anything
indicating we support VS2013, so it should be okay to unpin it.

`cc` 1.1.22 contains a fix that may help improve the high MSVC CI
failure rate [3], so we also have motivation to update to that point.

Rollup merge of #130477 - tmandry:revert-llvm-20-lto, r=tmandry 
Revert #129749 to fix segfault in LLVM

This reverts commit 8c7a7e346b, reversing changes made to a00bd75b6c.

Reported in https://github.com/rust-lang/rust/pull/129749#issuecomment-2354417960. `@nikic's` theory is that the LLVM API changed in a way that makes it impossible to use concurrently from multiple threads (https://github.com/llvm/llvm-project/pull/106427#issuecomment-2354783802). I pinged `@krasimirgg` who was fine with reverting.
