Improve const-folding error msg for static variables

The error message for an attempt to read a runtime variable
from optimize(WANTinterpret) is less informative than the CTFE one.
Improve the optimize() version, so that the test suite is ready for
the change to using CTFE throughout.
CTFE: Improve error message for static assert

by running optimize(0) first.
Currently static assert uses optimize(WANTinterpret) for const folding. This has
the side-effect of simplifying the expression before evaluating it, which makes
error messages nicer. If we simply change to using CTFE instead, the error
messages won't get simplified. So insert a call to optimize(0) before running CTFE.

Fix bug 10251 CTFE: Allow returning pointers to global statics of known value

Don't expand pointers to global variables.
They should stay as a SymOffExp, even if their value is known.
Fix bug 10252 CTFE: Generate error for shr/ushr/shl out of range

Use same behaviour as for const-folding.
CTFE: Allow creation (but not reading) of unions

It's currently possible to create unions in global scope but not in CTFE.
We can't support reading or writing members, but creation is OK.
CTFE: Allow VectorExp as a no-op
CTFE compile: Count total variable declarations

First step towards CTFE compilation. Walk over all
expressions in the function, searching for VarDeclarations and
checking the validity of the AST.
CTFE sanity check: verify no ErrorExps in AST

Before starting CTFE, we confirm that the AST is valid.
