Issue Description:

Simple string interpolation examples crash on Ubuntu in the REPL for some reason.

$ usr/bin/swift
Welcome to Swift version 4.2-dev (LLVM 04bdb56f3d, Clang b44dbbdf44, Swift aa19e11af7). Type :help for assistance.
 1> let amount = 3
amount: Int = 3
 2> let count = "I have \(amount) apples"
lldb: /home/swift-build/llvm/lib/IR/Value.cpp:404: void llvm::Value::doRAUW(llvm::Value *, bool): Assertion `New->getType() == getType() && "replaceAllUses of value with new value of different type!"' failed.
Stack dump:
0. Running pass 'Function Pass Manager' on module 'lldb_module'.
1. Running pass 'Swift ARC contraction' on function '@"$SSS19stringInterpolationS2Sd_tcfCTf4gd_n"'
[1] 91105 abort (core dumped) usr/bin/swift

Replicated on Ubuntu 16.04 and 14.04. This might be caused because optimizations are enabled in the REPL. Merging from upstream may fix the issue.

This bug was naturally fixed after downstreaming changes from master. Verified using the 6/29 toolchain for Ubuntu 16.04/14.04.

amount: Int = 3
  2> let count = "I have \(amount) apples"
count: String = "I have 3 apples"
