linker: Fix weak lang item linking with combination windows-gnu + LLD + LTO
In https://github.com/rust-lang/rust/pull/100404 this logic was originally disabled for MSVC due to issues with LTO, but the same issues appear on windows-gnu with LLD because that LLD uses the same underlying logic as MSVC LLD, just with re-syntaxed command line options.
So this PR just disables it for LTO builds in general.
Fix bug introduced by #9386#9386 introduced a potential out-of-bounds array access. Specifically, a location returned by `local_assignments` could have [`location.statement_index` equal to `mir.basic_blocks[location.block].statements.len()`](b8a9a507bf/clippy_utils/src/mir/mod.rs (L129)), in which case the location would refer to the block terminator:
b8a9a507bf/clippy_lints/src/dereference.rs (L1204-L1206)
I suspect the bug is not triggerable now, because of checks leading up to where it occurs. But a future code change could make it triggerable. Hence, it should be fixed.

Magic functions for writing to stdout/stderr.
This enables I/O in no_std contexts (or, really, any Miri-specific OS-independent context). Combined with the `abort` intrinsic it should allow a reasonable test framework in no_std.
**Question for maintainers:** So, the `no_std` panic test needs work, for two reasons:
- First, its stdout includes Miri's whole message about the abort intrinsic having been used. I guess whatever panic handler you use in `std` contexts exits cleanly without triggering this message. Comparing the entire output with backtrace as golden seems fragile.
- Second, likely for the same reason, the test framework appears to expect the test to exit successfully, when in fact it exits with status 1 due to the abort. This means the test doesn't actually pass right now.
What shall I do there?
Fix the bug of next_point in source_map
There is a bug in `next_point`, the new span won't move to next position when be called in the first time.
For this reason, our current code is working like this:
1. When we really want to move to the next position, we called two times of `next_point`
2. Some code which use `next_point` actually done the same thing with `shrink_to_hi`
This fix make sure when `next_point` is called, span will move with the width at least 1, and also work correctly in the scenario of multiple bytes.

rustdoc: remove no-op CSS `nav.sub { font-size: 1rem }`
This rule originated as a `font-size: 16px`, when body had `font-size: 13px` set in 4fd061c426.
It remained even when body's font size was bumped up to 16px, 4d5f4ff5e9, making the rule a no-op, and was carried forward when it was converted to 1rem in cc18120425.

This fixes a stable to stable regression that in my opinion is `P-critical` so, we probably want to backport it all the way up to stable.
This enables I/O in no_std contexts (or, really, any Miri-specific
OS-independent context). Combined with the `abort` intrinsic it should
allow a reasonable test framework in no_std.
