Fixed several issues relating to the static and const keywords

This fixes several miscompilations I discovering when attempting to transpile my c code. I also added debug functionality to the parse_error() function which will emit the line and file of where the error was generated. This is helpful for finding out which part of the parser is not working.

catch-bad-whitespace is destroying me lol

I squashed all the commits together since a lot of them were me just fixing whitespace issues caught by the CI

I'm not sure the exe code generator works well with (void) casts. Do you mind writing a small test for this? You can take a look at tests/_all/comma.c for an example, and can use ./run-tests.sh sh --match cast.c to run the test.

[VisenDev]

sure

I gave it a shot, i'm not really familiar with how the testing format works so it may take some tweaks

@laurenthuberdeau could you explain what the measure-file-size ci does?

[laurenthuberdeau]

Sure! measure-file-size is a script I use to track pnut's size. Because I kept breaking the script by accident, I added a CI check so I wouldn't have to bisect and find the commit that broke it next time I wanted to use it. You can run it locally using ./analysis/measure-file-size.sh.

If we look at the difference between the 2 files using diff build/measure/pnut-sh.sh build/measure/pnut-sh-preincluded.sh, we can see lots of diffs like this one:

2512c2512
<       defstr __str_102 "pnut.c"
---
>       defstr __str_102 "build/measure/pnut-sh.c"

Looks like the value of the __FILE__ macro is different between the 2 compilations. It doesn't really break the script, but it fails a sanity check I added in the script that compares the result of compiling pnut.c using pnut-sh and compiling a "packed" version of pnut.c where the includes have been expanded.

Maybe we can add a intermediate __SOURCE_FILE__ macro that can either expand to __FILE__ or to some hard coded string when some compilation option is used to work around this issue?

Edit: I made this PR to fix the script: #132
