It's in config/i386/t-i386.  And such files shouldn't really be using RTL 
themselves.  They are for pragmas, assertions, aspects of built-in 
functions that need handing at front-end time, controlling extensions for 
the C language, ... - all things that should be completed before the 
conversion to RTL.  (It's possible that some of them may store information 
for use by later stages of the compiler, but the code processing that 
information should be language-independent.)
