i386: Fix various testsuite issues

on 32bit long long support was sometimes broken.  This fixes
code-gen for long long values in switches, disables a x86-64 specific
testcase and avoid an undefined shift amount.  It comments out
a bitfield test involving long long bitfields > 32 bit; with GCC layout
they can straddle multiple words and code generation isn't prepared
for this.
