Title: Issue 8543 - simd literals need better CTFE support

Vector expressions in D are represented as ```cast(T[N])exp``` - this change lets CTFE be able to run interpret on the expression to expand it to it's underlying array literal.

Will add a test to the testsuite once have confirmed that there is no regressions from the autotester.
