[Bug c++/23789] [3.4/4.0/4.1 Regression] compilation error when template parameters have certain complexity

The problem here is that the NOP_EXPR case in tsubst is implemented by
build_nop, which unconditionally adds a NOP_EXPR.  We need to simplify the
NOP_EXPR away so that fold can do its job.  Perhaps we should have a CAST_EXPR
here, rather than a NOP_EXPR.  I'll work it out.
