Motiejus Jakštys 3c83549f77 parser: port enum/union/catch/switch/for/if declaration tests
Port tests:
- "enum declaration"
- "union declaration"
- "catch"
- "switch"
- "for if", "if for", "while if", "if while", "while for", "for while"
- "if"

Fix in parser.c:
- parsePtrPayload: handle multi-capture |a, *b|
- parseWhileStatement/parseForStatement: separate statement-context
  body parsing (block or assign expr + semicolon)

Deferred tests (need further work):
- "while" (full test) - var decl in while body context
- "for" (full test) - capture parsing edge case

zig0 aspires to be an interpreter of zig 0.15.1 written in C.

Testing

Quick test:

zig build

Debugging tips

Test runs infinitely? Build the test program executable:

$ zig build test -Dno-exec

And then run it, capturing the stack trace:

gdb -batch
-ex "python import threading; threading.Timer(1.0, lambda: gdb.post_event(lambda: gdb.execute('interrupt'))).start()"
-ex run
-ex "bt full"
-ex quit
zig-out/bin/test

You are welcome to replace -ex "bt full" with anything other of interest.
