Many `Type`s can correspond to the same `CType`, so this reduces the
number of used locals by 27760 when compiling only-c.
Also, disabled some tests that were only passing by accident and
shouldn't really be considered working.
After this, the last MSVC warnings are in behavior/bugs/529.zig:
behavior.c(37971): warning C4133: 'function': incompatible types - from 'A__8479 *' to 'A__8474 *'
behavior.c(37974): warning C4133: 'function': incompatible types - from 'A__8480 *' to 'A__8474 *'
* Support always_tail and never_tail/never_inline with a comptime callee using clang
* Support never_inline using gcc
* Support never_inline using msvc
Unfortunately, can't enable behavior tests because of the conditional support.
* Implement @fieldParentPtr on a union
* Refactor field access to ensure that it is handled consistently
* Remove `renderTypecast` as it is now behaves the same as `renderType`
This requires manual defines before C99 which may not have stdint.h.
Also have update-zig1 leave a copy of lib/zig.h in stage1/zig.h, which
allows lib/zig.h to be updated without needing to update zig1.wasm.
Note that since the object already existed with the exact same contents,
this completely avoids repo bloat due to zig.h changes.
- Fix assertion failure if AstGen failed on a multi-module file
- Cap number of per-error reference notes and total multi-module errors each at 5
- Always put "root of package" reference notes first
Resolves: #14499
lld accepts both syntaxes, but we were rejecting (and, before
3f7e9ff597a3514bb1c4f1900027c40682ac9f13, ignoring) the former.
In particular, "cargo-zigbuild" was broken since Rust
unconditionally adds "-znoexecstack" (not "-z noexecstack")
on non-Windows platforms.

* Scan from line start when finding tag in tokenizer
This resolves a crash that can occur for invalid bytes like carriage
returns that are valid characters when not parsed from within literals.
There are potentially other edge cases this could resolve as well, as
the calling code for this function didn't account for any potential
'pending_invalid_tokens' that could be queued up by the tokenizer from
within another state.
* Fix carriage return crash in multiline string
Follow the guidance of #38:
> However CR directly before NL is interpreted as only a newline and not part of the multiline string. zig fmt will delete the CR.
Zig fmt already had code for deleting carriage returns, but would still
crash - now it no longer does so. Carriage returns encountered before
line-feeds are now appropriately removed on program compilation as well.
* Only accept carriage returns before line feeds
Previous commit was much less strict about this, this more closely
matches the desired spec of only allow CR characters in a CRLF pair, but
not otherwise.
* Fix CR being rejected when used as whitespace
Missed this comment from ziglang/zig-spec#83:
> CR used as whitespace, whether directly preceding NL or stray, is still unambiguously whitespace. It is accepted by the grammar and replaced by the canonical whitespace by zig fmt.
* Add tests for carriage return handling
One of the main points of for loops is that you can safety check the
length once, before entering the loop, and then safely assume that every
element inside the loop is in bounds.
In master branch, the safety checks are incorrectly intact even inside
for loops. This commit fixes it. It's especially nice with multi-object
loops because the number of elided checks is N * M where N is how many
iterations and M is how many objects.
