'this' and 'base' both read the 'this' parameter of the function being
decompiled, but their resolve result did not say so: consumers that key on
ILVariableResolveResult (local-reference output, highlighting, hover) could
not connect the keyword to the variable, and the qualified/unqualified
spellings of the same access carried differently shaped annotations.
The resolver has no ILFunction and thus no variable to put into a
ThisResolveResult, so it stops synthesizing one: LookInCurrentType looks
the name up against the (self-parameterized) current type, which grants
the same protected access, and the annotation of an unqualified field
access is built from the translated target instead. ResolveThisReference
and ResolveBaseReference had no callers left and are removed.
