Few parser fixes

[kaleidawave]

• Fix capitalisation in ForLoopStatementInitialiser
• Fix for #154
• Fix for #161
• Fix for parser/examples/code_blocks_to_script.rs and .github/workflows/performance-and-size.yml
• Raise parse errors for trailing syntax in variable field currently not raising a parse error
• Add different array printing (see comment below)

Pretty formating of array

Currently if some structures including array have check to see if their content printed on the same line overflows a specific count. This works well (see parser/examples/pretty_printing.rs). However in a project I am working on I had a case where I have a array of lots of literals.

const x = [1, 1, 0, 0, 1, 0, 1, ... *etc* ]

as it breaks the max-line width threshold it is pretty printed as

const x = [
  1, 
  1, 
  0, 
  0, 
  1, 
  0, 
  1,
   ... *etc* 
]

I wonder if in this case it could be alternatively done in half-way manner, where the items are distributed?

const x = [
  1, 1, 0, 0, ...
  1, 0, 1, 0, ...
   ... *etc* 
]

Help @addisoncrump @jasikpark. Not sure why it is now requiring x86_64-unknown-linux-musl, when the rest of the tests run on x86_64-unknown-linux-gnu?

It was working yesterday (maybe a change in 1.79 that has just come through, not sure though) and not sure whether changing the CI dtolnay/rust-toolchain@stable target is a good fix or would even work?

You seem to have run into this: https://github.com/rust-fuzz/cargo-fuzz/issues/355

I'm surprised that hasn't already been fixed... I bumped the upstream issue.

[kaleidawave]

Need to look into this fuzzing issue before merge. Understand why broken, but not sure why now? There hasn't been an update to cargo-fuzz in a while? Manually setting the version hasn't seemed to work?

[kaleidawave]

Installing from the GitHub repository works? (cargo install --git https://github.com/rust-fuzz/cargo-fuzz.git). Only adds 18s to the action (to build the binary from source)? Should be okay, until https://github.com/rust-fuzz/cargo-fuzz/pull/365 is merged!

Are the issues linked resolved? You put "for" after "fix", so they didn't autoclose 😉
