Patch against dmd r685, sets missing precedences
Precedences for the following TOKs are not set, while they can be referenced by
expToCBuffer().
TOKassocarrayliteral, TOKcomplex80, TOKdelegate, TOKdotexp,
TOKdottype, TOKdsymbol, TOKfile, TOKhalt, TOKline,
TOKnewanonclass, TOKoverloadset, TOKremove, TOKtemplate.
This causes PREC_zero assertion failures in expToCBuffer(). The following cases
all trigger the assertion failure.
--------------------
template Q(s...) { alias s q; }
class C {}
enum assocarrayliteral = Q!( [1:2] ).q.stringof;
enum complex80 = Q!( 1+1.0i ).q.stringof;
enum dottype = Q!( C.Object.toString ).q.stringof;
enum halt = (assert(0), 0).stringof; // ICE w/ -release
enum remove = Q!( [1:2].remove(1) ).q.stringof;
enum templat = Q!( Q ).q.stringof;
--------------------
The halt case depends on bug 4925. dottype and remove are ice-on-invalid.
Although I couldn't find any offending case for the other TOKs, I think it's
better to define reasonable precedences for all the said TOKs.
The attached patch also fixes bug 4912 and bug 4914.

This is a regression introduced in 2.049, and it also applies to D1 (need to replace 'enum' with 'const' for the D1 test case).
