Move syntax::ext to a syntax_expand and refactor some attribute logic
Part of https://github.com/rust-lang/rust/pull/65324.
r? @petrochenkov

- Compatible with Emscripten 1.38.46-upstream or later upstream.
- Refactors the Emscripten target spec to share code with other wasm
targets.
- Replaces the old incorrect wasm32 C call ABI with the correct one,
preserving the old one as wasm32_bindgen_compat for wasm-bindgen
compatibility.
- Updates the varargs ABI used by Emscripten and deletes the old one.
- Removes the obsolete wasm32-experimental-emscripten target.
- Uses EMCC_CFLAGS on CI to avoid the timeout problems with #63649.

Several changes to the codegen backend organization
* Split functions from values in cg_ssa `BackendTypes`.
* Remove `is_const_integral` function from `ConstMethods`.
* Actually register the invalid monomorphization of intrinsic long diagnostic and remove the `diagnostics` method from `CodegenBackends`, as it was unused.
* Add cg_ssa and cg_utils provided methods to `default_provide`, so codegen backend don't have to do it themself.

pnkfelix:targetted-fix-for-always-marking-rust-abi-unwind-issue-64655, r=alexcrichton
Always mark rust and rust-call abi's as unwind
PR #63909 identified a bug that had been injected by PR #55982. As discussed on https://github.com/rust-lang/rust/issues/64655#issuecomment-537517428 , we started marking extern items as nounwind, *even* extern items that said they were using "Rust" or "rust-call" ABI.
This is a more targeted variant of PR #63909 that fixes the above bug.
Fix #64655
----
I personally suspect we will want PR #63909 to land in the long-term
But:
* it is not certain that PR #63909 *will* land,
* more importantly, PR #63909 almost certainly will not be backported to beta/stable.
The identified bug was more severe than I think anyone realized (apart from perhaps @gnzlbg, as noted [here](https://github.com/rust-lang/rust/pull/63909#issuecomment-524818838)).
Thus, I was motivated to write this PR, which fixes *just* the issue with extern rust/rust-call functions, and deliberately avoids injecting further deviation from current behavior (you can see further notes on this in the comments of the code added here).

Add llvm.sideeffect to potential infinite loops and recursions
LLVM assumes that a thread will eventually cause side effect. This is
not true in Rust if a loop or recursion does nothing in its body,
causing undefined behavior even in common cases like `loop {}`.
Inserting llvm.sideeffect fixes the undefined behavior.
As a micro-optimization, only insert llvm.sideeffect when jumping back
in blocks or calling a function.
A patch for LLVM is expected to allow empty non-terminate code by
default and fix this issue from LLVM side.

Disable stack probe when thread sanitizer is enabled
When thread sanitizer instrumentation is enabled during compilation of
stack probe function, the function will be miscompiled and trigger
segmentation fault at runtime. Disable stack probes when tsan is
enabled.

Revert #63649 - "Upgrade Emscripten targets to use upstream LLVM backend"
This change caused the runtime of the linux-asmjs builder to nearly double from 2+ hours to about 4 hours, which happens to be the bors timeout. (It made it in barely under 4 hours when it was merged.) This is causing timeouts on all new changes.
This reverts commit 7870050796e5904a0fc85ecbe6fa6dde1cfe0c91, reversing
changes made to 2e7244807a7878f6eca3eb7d97ae9b413aa49014.

Upgrade Emscripten targets to use upstream LLVM backend
- Refactors the Emscripten target spec to share code with other wasm
targets.
- Replaces the incorrect wasm32 C call ABI with the old asmjs
version, which is correct for both wasm32 and JS.
- Updates the varargs ABI used by Emscripten and deletes the old one.
- Removes the obsolete wasm32-experimental-emscripten target.
- Temporarily makes Emscripten targets use panic=abort by default
because supporting unwinding will require an LLVM patch.

SelfProfiler API refactoring and part one of event review
This PR refactors the `SelfProfiler` a little bit so that most profiling methods are RAII-based. The codegen backend code already had something similar, this refactoring pulls this functionality up into `SelfProfiler` itself, for general use.
The second commit of this PR is a review and update of the existing events we are already recording. Names have been made more consistent. CGU names have been removed from event names. They will be added back in when function parameter recording is implemented.
There is still some work to be done for adding new events, especially around trait resolution and the incremental system.

No StableHasherResult everywhere
This removes the generic parameter on `StableHasher`, instead moving it to the call to `finish`. This has the side-effect of making all `HashStable` impls nicer, since we no longer need the verbose `<W: StableHasherResult>` that previously existed -- often forcing line wrapping.
This is done for two reasons:
* we should avoid false "generic" dependency on the result of StableHasher
* we don't need to codegen two/three copies of all the HashStable impls when they're transitively used to produce a fingerprint, u64, or u128. I haven't measured, but this might actually make our artifacts somewhat smaller too.
* Easier to understand/read/write code -- the result of the stable hasher is irrelevant when writing a hash impl.
