rust_for_linux: -Zregparm=<N> commandline flag for X86 (rust-lang#116972)

Command line flag `-Zregparm=<N>` for X86 (32-bit) for rust-for-linux: rust-lang#116972
Implemented in the similar way as fastcall/vectorcall support (args are marked InReg if fit).

`rt::Argument`: elide lifetimes

Always specify `llvm_abiname` for RISC-V targets

For RISC-V targets, when `llvm_abiname` is not specified LLVM will infer the ABI from the target features, causing rust-lang#116344 to occur. This PR adds the correct `llvm_abiname` to all RISC-V targets where it is missing (which are all soft-float targets), and adds a test to prevent future RISC-V targets from accidentally omitting `llvm_abiname`. The only affect of this PR is that `-Ctarget-feature=+f` (or similar) will no longer affect the ABI on the modified targets.

shave 150ms off bootstrap

This starts `git` commands inside `GitInfo`and the submodule updates in parallel. Git should already perform internal locking in cases where it needs to serialize a modification.

```

This should help with the rust-analyzer setup which issues many individual `./x check` calls. There's more that could be done but these were the lowest-hanging fruits that I saw.

Move const trait tests from `ui/rfcs/rfc-2632-const-trait-impl` to `ui/traits/const-traits`

I found the old test directory to be somewhat long to name, and I don't think it's necessary to put an experimental implementation's tests under an rfc which is closed.

r? fee1-dead

Breaking this out of rust-lang#131985 so that PR doesn't touch 300 files.
