Fix the problem (dmd 2.030)

TemplateInstance::semanticTiargs() does not expand tuples which are passed as
expressions (e.g. TypeExp). As a result, this valid code causes an ICE:
--------------------
import std.typetuple;
template List(lst...) { alias lst list; }
alias TypeTuple!(List!(void)) A;
alias TypeTuple!(A[0].list) B;
--------------------
ta = 39, (int)
assert template.c(4088) global.errors
--------------------
