Motiejus Jakštys 97c9fb6378 parser: implement asm parsing, port formatting tests

Implement in parser.c:
- parseAsmExpr: asm_simple and asm nodes with outputs, inputs,
  clobbers (including legacy string clobber format)
- parseAsmOutputItem, parseAsmInputItem helper functions

Port tests:
- "preserve spacing"
- "return types"
- "imports"
- "global declarations"
- "extern declaration"
- "function attributes"
- "nested pointers with ** tokens"
- "test declaration"
- "top-level for/while loop"
- Various error set, switch prong, comment tests

Note: asm test cases that require asm_legacy AST node (not yet in
ast.h) are deferred.

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.
