This Cl updates all of the expression methods to accept a pre stream.
The prestream is used to output code _before_ the statement which is
executing the expression. This will allow for unwrapping logical and and
or expressions and emitting them prior to their expression.

If there is a continuing block we pull the variables declared in the
loop up into the scope outside the loop. This allows those variables to
be used in the continuing block.
We pull out all variables instead of detecting ones which are only used
in continuing as that's easier and still correct.

Follow the actual SPIR-V type when computing a composite extract
instad of the canonicalized view in the optimizer's type manager.
Do this so we can generate the correct member name for a struct,
rather than using the member name for the other representative
struct type. The optimizer's type canonicalizer is insensitive to
struct member names.
Prompted by tint:213, for which the original case was an
access chain.
