ac4737b1 - [SILGen] When emitting an apply, don't decode the dbgloc unconditionally.

[SILGen] When emitting an apply, don't decode the dbgloc unconditionally. Turns out it's really expensive and not really needed. On my machine the testcase reported in SR-7691 goes down from 24 seconds to 2 seconds after this change. <rdar://problem/40258978>
