getSymbolAtLocation returns wrong symbol for import alias in RHS of "import ="

[jeffreymorlan]

module SomeModule { export class SomeClass {} }

import M = SomeModule;  // or import M = require(...)
import C = M.SomeClass;

On the M identifier in M.SomeClass, getSymbolAtLocation returns the SomeModule module symbol, rather than the alias M to it.

This affects renaming, find references, and occurrence highlighting:

• If you select the M in import M = ..., the second M will not be found
• If you select the M in import C = M.SomeClass, the first M will not be found, but the two SomeModule references will be found instead.

Yeah, rename on aliases seems to be extremely broken.
