Motiejus Jakštys 50ea349da4 parser: port switch, slice, array literal, formatting tests

Port tests:
- "switch cases trailing comma"
- "slice align"
- "add trailing comma to array literal"
- "first thing in file is line comment"
- "line comment after doc comment"
- "bit field alignment"
- "nested switch"
- "float literal with exponent"
- "if-else end of comptime"
- "nested blocks"
- "statements with comment between"
- "statements with empty line between"
- "ptr deref operator and unwrap optional operator"

Fix in parser.c:
- switch_case SubRange stored via addExtra (not inline)
- Switch case body uses parseAssignExpr (not expectExpr)
- TOKEN_PERIOD_ASTERISK for deref in parseSuffixOp

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.
