0ecc6332b4eb1ced547ffa38f57471134aaa4d13 improved things for thumb2, but thumb1
has a much smaller permissible instruction set. This commit makes that work.
I've seen implementations in the wild that send 'Upgrade: WebSocket',
which currently fails the handshake.
From https://datatracker.ietf.org/doc/html/rfc6455:
"If the response lacks an |Upgrade| header field or the |Upgrade| header
field contains a value that is not an ASCII case-insensitive match for
the value "websocket", the client MUST _Fail the WebSocket Connection_."
The previous API used `std.testing.fuzzInput(.{})` however that has the
problem that users call it multiple times incorrectly, and there might
be work happening to obtain the corpus which should not be included in
coverage analysis, and which must not slow down iteration speed.
This commit restructures it so that the main loop lives in libfuzzer and
directly calls the "test one" function.
In this commit I was a little too aggressive because I made the test
runner export `fuzzer_one` for this purpose. This was motivated by
performance, but it causes "exported symbol collision: fuzzer_one" to
occur when more than one fuzz test is provided.
There are three ways to solve this:
1. libfuzzer needs to be passed a function pointer instead. Possible
performance downside.
2. build runner needs to build a different process per fuzz test.
Potentially wasteful and unclear how to isolate them.
3. test runner needs to perform a relocation at runtime to point the
function call to the relevant unit test. Portability issues and
dubious performance gains.

This commit modifies the `multiline_string_literal_line`, `doc_comment`,
and `container_doc_comment` tokens to no longer include the line ending
as part of the token. This makes it easier to handle line endings (which
may be LF, CRLF, or in edge cases possibly nonexistent) consistently.
In the two issues linked above, Autodoc was already assuming this for
doc comments, and yielding incorrect results when handling files with
CRLF line endings (both in Markdown parsing and source rendering).
Applying the same simplification for multiline string literals also
brings `zig fmt` into conformance with
https://github.com/ziglang/zig-spec/issues/38 regarding formatting of
multiline strings with CRLF line endings: the spec says that `zig fmt`
should remove the CR from such line endings, but this was not previously
the case.
Broadly speaking, versions 6, 7, and 8 are the ones that are in common use. Of
these, v7 is what you'll typically see for 32-bit Arm today. So let's actually
make sure that that's what we're testing.
