Jonas Devlieghere 49ff4d9041 [DWARF] Unclamp line table version on Darwin for v5 and later.
On Darwin we pin the DWARF line tables to version 2. Stop doing so for
DWARF v5 and later.

; Source text provided by IR should be passed through to asm.
; It is emitted to an object file only for DWARF 5 or later.
;
; Note that on Darwin for DWARF 4 or earlier, the line table version is clamped
; to version 2. However that doesn't affect the output checked in this test.
