Where are (syntax x) forms compiled with the old vector based
implementation of syntax objects (guile 2.0.11 or 2.2.0)? The
structure type for the syntax objects is defined in ice-9/psyntax.scm
but I can't find code for the syntax form.

'syntax' is a core form of the psyntax macro expander. In both 2.0 and
2.2, the code to handle expansion of 'syntax' forms is in psyntax.scm,
beginning with:
(global-extend 'core 'syntax
Although in 2.2 the text above is split between two lines:
(global-extend
'core 'syntax
