bivariate	Applies the "bivariance relationship" to two types and/or regions. If (A,B) are bivariant then either A <: B or B <: A. It occurs when type/lifetime parameters are unconstrained. Usually this is an error, but we permit it in the specific case where a type parameter is constrained in a where-clause via an associated type.

TypeTrace	The trace designates the path through inference that we took to encounter an error or subtyping constraint.

LateBoundRegionConversionTime	Times when we replace late-bound regions with variables:
RegionVariableOrigin	Reasons to create a region inference variable
SubregionOrigin	The origin of a `r1 <= r2` constraint.
TypeOrigin	Why did we require that the two types be related?
ValuePairs	See `error_reporting.rs` for more details
fixup_err

can_mk_eqty
can_mk_subty
common_supertype	Computes the least upper-bound of `a` and `b`. If this is not possible, reports an error and returns ty::err.

Bound
SkolemizationMap	A map returned by `skolemize_late_bound_regions()` indicating the skolemized region that each late-bound region was replaced with.
