2023-06-24	disable some layout optimizations for unsizable structs	The 8472	-42/+48

2023-06-24	Make struct layout not depend on unsizeable tail	Lukas Markeffsky	-2/+6

2023-05-16	Avoid `&format("...")` calls in error message code.	Nicholas Nethercote	-2/+2
	Error message all end up passing into a function as an `impl Into<{D,Subd}iagnosticMessage>`. If an error message is creatd as `&format("...")` that means we allocate a string (in the `format!` call), then take a reference, and then clone (allocating again) the reference to produce the `{D,Subd}iagnosticMessage`, which is silly. This commit removes the leading `&` from a lot of these cases. This means the original `String` is moved into the `{D,Subd}iagnosticMessage`, avoiding the double allocations. This requires changing some function argument types from `&str` to `String` (when all arguments are `String`) or `impl Into<{D,Subd}iagnosticMessage>` (when some arguments are `String` and some are `&str`).

2023-05-05	Review feedback	Luqman Aden	-13/+22

2023-05-05	Incorporate review feedback from 103926.	Luqman Aden	-38/+33

2023-05-05	Do not use scalar layout if there are ZSTs with alignment > 1	Oli Scherer	-20/+42

2023-04-28	layout-alignment-promotion logic should depend on the niche-bias	The 8472	-7/+22
	For start-biased layout we want to avoid overpromoting so that the niche doesn't get pushed back. For end-biased layout we want to avoid promoting fields that may contain one of the niches of interest.

2023-04-27	try two different niche-placement strategies when layouting univariant structs	The 8472	-6/+70

2023-04-27	refactor: extract function	The 8472	-214/+220

2023-04-18	Store hashes in special types so they aren't accidentally encoded as numbers	Ben Kimock	-1/+2

2023-04-16	Various minor Idx-related tweaks	Scott McMurray	-4/+3
	Nothing particularly exciting here, but a couple of things I noticed as I was looking for more index conversions to simplify.
2023-04-04	Use `FieldIdx` in `FieldsShape`	Scott McMurray	-40/+35
	Finally got to the main motivating example from the MCP :)
2023-04-02	Use `&IndexSlice` instead of `&IndexVec` where possible	Scott McMurray	-2/+2
	All the same reasons as for `[T]`: more general, less pointer chasing, and `&mut IndexSlice` emphasizes that it doesn't change length.
2023-03-25	Refactor: `VariantIdx::from_u32(0)` -> `FIRST_VARIANT`	Scott McMurray	-9/+9
	Since structs are always `VariantIdx(0)`, there's a bunch of files where the only reason they had `VariantIdx` or `vec::Idx` imported at all was to get the first variant. So this uses a constant for that, and adds some doc-comments to `VariantIdx` while I'm there, since it doesn't have any today.
2023-01-21	Remove some superfluous type parameters from layout.rs.	Michael Benfield	-75/+71
	Specifically remove V, which can always be VariantIdx, and F, which can always be Layout.
2022-12-01	Remove useless borrows and derefs	Maybe Waffle	-5/+5
