  LowerTypeTests: Switch to emitting one inline asm call per jump table entry.

With the previous approach of emitting one inline asm call for all jump
table entries we would encounter SelectionDAG's limit on the number
of operands per node (65536) when the number of jump table entries
exceeded that number. Fix the problem by switching to one inline asm
per jump table entry so that each DAG node only needs one operand.
