[PATCH v3] i386: Zero extend 32-bit address to 64-bit with option -mx32 -maddress-mode=long. [PR 117418]

[Hu, Lin1]

OK, added check for target.

Bootstrapped and Regtested on x86-64-linux-pc-gnu, OK for trunk?

BRs,
Lin

-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.
