Reproducible: 100%

To reproduce, run "gcc -O -fPIC -c bug.c" (I will attach a small self-contained
bug.c shortly).

Expected: it compiles (or produces an error message if the source is not a valid
C program).

Actual:

/tmp/ccMEmtFi.s: Assembler messages:
/tmp/ccMEmtFi.s:14: Error: suffix or operands invalid for `movabs'
Exit 1

This bug comes up when trying to compile OCaml (current CVS head) on x86_64
under a recent Rawhide tree.

Note that both -O and -fPIC options are necessary to reproduce (without one or
both of them, the file compiles fine).
