Andrew Trick df7326d790 Fix SILType::isEscapable for box types. ...

SILBoxTypes have their own generic signature and substitution
map. This means that every time we query isEscapable or mayEscape, we
need to extract the type of the box's field and perform type
substitution so that the AST query only sees types from the function's
generic environment.

Fixes rdar://124179106 (Assertion failed in SIL:
(!type->hasTypeParameter() && "caller forgot to mapTypeIntoContext!"))
