[Bug target/20928] New: ICE: unrecognoizable insns


Compiling clisp with gcc 4 CVS fails with the following ICE.  This is a
regression from GCC 3.3.

$ gcc -fPIC -D_GNU_SOURCE  -W -Wswitch -Wcomment -Wpointer-arith -Wimplicit
-Wreturn-type   -O -DUNICODE -DDYNAMIC_FFI -DDYNAMIC_MODULES -DNO_SIGSEGV -I. -c
spvw.c -save-temps -v
Using built-in specs.
