Small structs (<= 64 bits) were being passed with their fields split into separate arguments instead of being packed into register-sized chunks. This caused ABI mismatches. The fix properly casts small aggregates to consecutive register-sized chunks using Uniform::consecutive(), matching the Hexagon C ABI where small structs are packed into R1:0 register pair. This fixes tests like extern-pass-TwoU16s.rs and extern-pass-TwoU8s.rs.
Correct the handling of aggregate types in extern "C" functions to match the Hexagon ABI specification: - Aggregates up to 32 bits: passed/returned in a single register (R0) - Aggregates 33-64 bits: passed/returned in a register pair (R1:R0) - Aggregates > 64 bits: passed on stack via byval, returned via sret This fixes all tests/ui/abi/extern/ tests for Hexagon, including: - extern-pass-TwoU8s, extern-pass-TwoU16s, extern-pass-TwoU32s - extern-pass-TwoU64s, extern-pass-FiveU16s - extern-return-TwoU8s, extern-return-TwoU16s, extern-return-TwoU32s - extern-return-TwoU64s, extern-return-FiveU16s
…ckwards compatability
…stion, r=lcnr Detect existing turbofish on method calls to suppress useless suggestion `expr_inferred_arg_iter` hardcoded `have_turbofish: false` for `MethodCall` expressions, while the `Path` case properly checked for existing type arguments via `segment.args`. This meant the "consider specifying the generic arguments" suggestion always fired on method calls, even when the user already had a turbofish, producing a suggestion that just rewrote user syntax into fully qualified form without resolving anything. Fixes rust-lang#153732. cc @eggyal
Remove `MTLock` This removes the `MTLock` type and replaces it users with the regular `Lock`. It no longer makes sense now that we don't have a compile-time toggle for parallelism.

…Kobzol Fix that `./x test --no-doc` actually keeps the same behaviour for backwards compatability In rust-lang#153143 the `./x test --no-doc` flag was renamed to `--all-targets`. I added a commit that keeps the `--no-doc` flag for backwards compatibility, but unfortunately I forgot to actually keep the behaviour the same, which is fixed by this PR. r? @Kobzol
