Motiejus Jakštys cb4be73acb parser: add enum, union, literal, struct doc comment tests
Port tests from upstream parser_test.zig:
- "empty enum decls" (with extern/packed modifiers)
- "empty union decls" (with extern/packed/enum modifiers)
- "enum literal"
- "character literal larger than u8"
- "infix operator and then multiline string literal" (2 tests)
- "correctly space struct fields with doc comments"
- "aligned struct field"
- "comment to disable/enable zig fmt first"

Implement in parser.c:
- extern/packed modifiers before struct/union/enum in
  parsePrimaryTypeExpr

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.
