rustc_target: Mark UEFI targets as `is_like_windows`/`is_like_msvc`
And document what `is_like_windows` and `is_like_msvc` actually mean in more detail.
Addresses FIXMEs left from https://github.com/rust-lang/rust/pull/71030.

rustc_parse: Remove optimization for 0-length streams in `collect_tokens`
The optimization conflates empty token streams with unknown token stream, which is at least suspicious, and doesn't affect performance because 0-length token streams are very rare.
r? `@Aaron1011`
This allows constant propagation to evaluate `size_of` and `wrapping_*`,
and unreachable propagation to propagate a call to `unreachable`.
The lowering is performed as a MIR optimization, rather than during MIR
building to preserve the special status of intrinsics with respect to
unsafety checks and promotion.
Previously EOVERFLOW handling was only applied for io::copy specialization
but not for fs::copy sharing the same code.
Additionally we lower the chunk size to 1GB since we have a user report
that older kernels may return EINVAL when passing 0x8000_0000
but smaller values succeed.
Android builds use feature level 14, the libc wrapper for splice is gated
on feature level 21+ so we have to invoke the syscall directly.
Additionally the emulator doesn't seem to support it so we also have to
add ENOSYS checks.
Fix and re-enable two coverage tests on MacOS
Note, in the coverage-reports test, the comment about MacOS was wrong.
The setting is based on config.toml llvm `optimize` setting. There
doesn't appear to be any environment variable I can check, and I
don't think we should add one. Testing the binary itself is a more
reliable way to check anyway.
For the coverage-spanview test, I removed the dependency on sed
altogether, which is much less ugly than trying to work around the
MacOS sed differences.
I tested these changes on Linux, Windows, and Mac.

Rustdoc check option
The ultimate goal behind this option would be to have `rustdoc --check` being run when you use `cargo check` as a second step.

Add type to `ConstKind::Placeholder`
I simply threaded `<'tcx>` through everything that required it. I'm not sure whether this is the correct thing to do, but it seems to work.

Eliminate some temporary vectors
This PR changes `get_item_attrs` and `get_item_variances` to return iterator impls instead of vectors. On top of that, this PR replaces some seemingly unnecessary vectors with iterators or SmallVec, and also reserves space where we know (the minimum) number of elements that will be inserted. This change hopes to remove a few heap allocations and unnecessary copies.
Bump version number to 1.50.0
First PR of the release process of Rust 1.48.0. All PRs landed after this one will be included in Rust 1.50.0.
