Function dmd.statementsem.makeTupleForeach
Type check and unroll foreach over an expression tuple as well
as static foreach statements and static foreach
declarations. For static foreach statements and `static
foreach` declarations, the visitor interface is used (and the
result is written into the result field.) For `static
foreach` declarations, the resulting Dsymbols* are returned
directly.

The unrolled body is wrapped into a
- UnrolledLoopStatement, for foreach over an expression tuple.
- ForwardingStatement, for static foreach statements.
- ForwardingAttribDeclaration, for static foreach declarations.
static foreach variables are declared as STC, such
that they are inserted into the local symbol tables of the
forwarding constructs instead of forwarded. For `static
foreach` with multiple foreach loop variables whose aggregate
has been lowered into a sequence of tuples, this function
expands the tuples into multiple STC static foreach
variables.
