i386: Zero extend 32-bit address to 64-bit with option -mx32 -maddress-mode=long. [PR 117418]

Browse source 
-maddress-mode=long let Pmode = DI_mode, so zero extend 32-bit address to
64-bit and uses a 64-bit register as a pointer for avoid raise an ICE.

gcc/ChangeLog:

	PR target/117418
	* config/i386/i386-expand.cc (ix86_expand_builtin): Convert
	pointer's mode according to Pmode.

gcc/testsuite/ChangeLog:

	PR target/117418
	* gcc.target/i386/pr117418-1.c: New test.
