9040b06ed2 Auto merge of #28286 - matklad:remove-dead-code, r=eddyb
There is a dead code in libsyntax/parser/parse.rs, when parsing structs.

Two functions are involved:

* [parse_item_struct](cd9c9f048f/src/libsyntax/parse/parser.rs (L4691))
* [parse_tuple_struct_body](cd9c9f048f/src/libsyntax/parse/parser.rs (L4769))

The problem is that both functions handle the case with unit structs. But because
`parse_tuple_struct_body` is called from `parse_item_struct`, it never faces
this case.

This PR removes unit struct case from `parse_tuple_struct_body` function. I tested with `make -j8 check-statge1`.

This commit does some refactoring to make almost all of the `std::rt` private.
Specifically, the following items are no longer part of its API:

* DEFAULT_ERROR_CODE
* backtrace
* unwind
* args
* at_exit
* cleanup
* heap (this is just alloc::heap)
* min_stack
* util

The module is now tagged as `#[doc(hidden)]` as the only purpose it's serve is
an entry point for the `panic!` macro via the `begin_unwind` and
`begin_unwind_fmt` reexports.

fbeef72163 Auto merge of #28354 - dotdash:slow_plat, r=eddyb
When the inliner has to decided if it wants to inline a function A into an
internal function B, it first checks whether it would be more profitable
to inline B into its callees instead. This means that it has to analyze
B, which involves checking the assumption cache. Building the assumption
cache requires scanning the whole function, and because inlining
currently clears the assumption cache, this scan happens again and
again, getting even slower as the function grows from inlining.

As inlining the huge find functions isn't really useful anyway, we can
mark them as noinline, which skips the cost analysis and reduces compile
times by as much as 70%.

llvm seems to be having some trouble optimizing the iterator-based string comparsion method into some equivalent to memcmp. This explicitly calls out to the memcmp intrinisic in order to allow llvm to generate better code. In some manual benchmarking, this memcmp-based approach is 20 times faster than the iterator approach.

5c56887903 Auto merge of #28331 - semarie:openbsd-configure-egcc, r=alexcrichton
under OpenBSD, it could be have present multiples versions of gcc compiler:
  - gcc-4.2 (with patchs) : c/c++ compiler present in `/usr/bin`. It is unusable to build recent LLVM (so rustc too).
  - gcc/g++ -4.9 : c/c++ compiler, installed as third-party with "ports" mechanism. The compiler is installed in `/usr/local` as `egcc` (and `eg++`).

this PR adds probing for `egcc` for `CFG_GCC`, if the first probed `gcc` is too old. It will set `CC` and `CXX` too, in order to pass the variables to LLVM configure if builded.

please note this PR is a first step in order to build rustc under OpenBSD with unpatched tree.
