    testsuite: Fix up pr106070.c test [PR106070]
    
    The test FAILs on 32-bit targets, because when unsigned long
    is 32-bit, (unsigned long) -1 isn't 0xffffffffffffffff.
    The options to fix this would be either using -1UL, or switch
    to unsigned long long and using -1ULL, I chose the latter because
    the test then FAILs in r13-1242 even on 32-bit targets.
    And while at it, some deobfuscation and formatting tweaks.

            * gcc.dg/torture/pr106070.c: Use unsigned long long instead of
            unsigned long and -1ULL instead of 0xffffffffffffffff, deobcuscate
            and improve formatting.
