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.

`.len()` returns length in bytes so it overestimates the required space

It's now unused, even with -Zquery-dep-graph

Fix the start/end byte positions in the compiler JSON output

Track the changes made during normalization in the `SourceFile` and use this information to correct the `start_byte` and `end_byte` fields in the JSON output.

This should ensure the start/end byte fields can be used to index the original file, even if Rust normalized the source code for parsing purposes. Both CRLF to LF and BOM removal are handled with this one.

The rough plan was discussed with @matklad in rust-lang/rustfix#176 - although I ended up going with `u32` offset tracking so I wouldn't need to deal with `u32 + i32` arithmetics when applying the offset to the span byte positions.

Fixes rust-lang#65029

Remove loaded_from_cache map from DepGraph

It's now unused, even with -Zquery-dep-graph

From https://github.com/rust-lang/rust/pull/63756/files#r316039379 -- it'll simplify that PR to get this landed separately so we can just remove some of the code that it touches.

Remove query-related macros

The query system has a few macros that only have one or two call sites, and I find they hurt readability. This PR removes them.
