91f8bc5b2a SIL.rst: Briefly discuss the cdecl and objc conventions. 
C types are always trivial and C function signatures don't get mangled by the platform ABI at the SIL level. ObjC methods uncurry left-to-right, "_cmd" is magicked away, and they follow ARC's ownership rules for reference counting.

ac50a32428 SIL.rst: Remove absurd grammar example. 
None of the instructions I used to demonstrate the operand syntax actually use it. That's dumb.

Also refactor the grammar to fix an inaccurate use of 'sil-value'. We allow the '#n' value index even in places we don't require a type, but not for instruction or bb argument defs.

e673b0cf55 SIL.rst: Update in response to DaveA comments. 
Avoid overspecifying optimization/diagnostic passes because those aren't nailed down yet. Don't use "shared" to refer to boxed variables; it's meaningless in this context.

SIL has it, though a perfect Swift program written against a perfect Swift standard library run through perfect optimization passes should never emit it.
