Bug 15789 – ICE Assert in TemplateInstance semanticTiargs

This issue was hard to reduce to a small testcase, and somehow only crashes when two files are compiled at the same time, and the InputRange type is in its own file. inputrangetype.d: ``` struct InputRange { ubyte[] front() {} void popFront() {} bool empty() {} } ``` foo.d: ``` import std.digest.md; import inputrangetype; void foo() { md5Of(InputRange()); } ``` bar.d: ``` import std.traits; import std.digest.md; import inputrangetype; void bar() { fullyQualifiedName!(md5Of!InputRange); } ``` Compiled with this exact cmdline (reversing source files 'fixes' it): dmd foo.d bar.d it crashes the compiler, with [email protected](7192): Assertion failure https://github.com/D-Programming-Language/dmd/blob/204253b3111166cd30d5e42d936ed5f138920ff8/src/dtemplate.d#L7192 DMD64 D Compiler v2.070-devel-204253b OS X El Capitan

Better fix (IMO): https://github.com/D-Programming-Language/dmd/pull/5520
