596545 - nanojit: Add more calling-convention tests.

Status: RESOLVED FIXED

(Core Graveyard :: Nanojit, defect)

Attachment: Add calling tests with mixed argument types.

These tests exercise the ARM calling convention(s). They are valid for other architectures, but it might be worth adding more tests that exercise similar paths in other back-ends.

The names calld[234] don't make much sense since there are a mix of int and double args.  Maybe callid[123]?  Otherwise it looks good.
