Issue Description:

print("hello") [123]

// Compiling this (invalid) program with the default toolchain of Xcode 9.3
// will produce an expected compile time error (although perhaps with a
// somewhat unexpected error message):
// Value of tuple type '()' has no member 'subscript'

// But compiling it with a recent development snapshot will crash the compiler.

// (Btw, perhaps this is something that should be expected, eg given that the
// development snapshots are not built in the same way as official toolchains?
// If so, maybe it's not worth filing this kind of compiler crashers?)
