Issue Description:

When using the Swift 3.1 compiler, attempts to use inline functions (particularly NSRange) can end up crashing the Swift compiler with something like:

1.	While running pass #​884 SILModuleTransform "Mandatory Inlining".
2.	While deserializing decl #​502 (XREF)in 'Foundation'
3.	Cross-reference to module 'Foundation'
	... NSMutableData
	... length
	... with type Int
4.	If you're seeing a crash here, check that your SDK and dependencies match the versions used to build 'Foundation'

Steps:
- Using Xcode 8.3 beta 2 or beta 3
- Extract the attached zip of source
- Open OmniGroup/Workspaces/OmniFrameworks.xcworkspace
- Build
- Build completes successfully
- Search for "Crashes compiler"
- Remove the #if false wrapper around any of the matches
- Build
- Compiler crashes

This code builds fine in Xcode 8.2.1.

This seems to be fixed on master, but now we have to figure out what fixed it.

Hm, unfortunately the fix seems to be the reworking of Foundation.Data to use itself as its own SubSequence type, something too big to cherry-pick into Swift 3.1. There's an actual bug here that we'd need to fix instead.

It looks like the presence of the -setLength: method in OFByteAcceptor is throwing off the import of the readwrite length property. This is backwards, of course; we shouldn't mirror in any protocol members until after the regular members have been imported.

Lousy workaround: declare @property NSUInteger length in OFByteAcceptor instead of -setLength:, even though the protocol doesn't technically need it.
