8d8577e5b0 [SIL] Removed Indirect_In_Constant convention. 
It is no different from @in.

Continue parse @in_constant in textual and serialized SIL, but just as
an alias for @in.

ca43d71769 [OpaqueValues] Fixed index of self argument. 
Previously, SILFunction_getSelfArgumentIndex was directly using the
function type rather than interacting with the function convention.
Here, it is made to interact with the convention.

4a60ea809b Add some Swift SIL infrastructure 
* In `ApplySite`: `argumentOperands` and `isCalleeOperand`
* In `ArgumentConvention`: `isIndirect`, `isIndirectIn` and `isGuaranteed`
* In `Function`: `isDefinition`, `numParameterArguments`, `numArguments`, `getArgumentConvention`, `effectAttribute`
* In `Type`: `isFunction` and `isCalleeConsumedFunction`
* In `Instruction`: `hasUnspecifiedSideEffects`
* New bridged instructions: `EndApplyInst` and `AbortApplyInst`
* `LoadInst.ownership`
* `BeginAccessInst.isStatic`
* make the `Allocation` protocol a `SingleValueInstruction` (instead of `AnyObject`)
