testsuite: Fix up pr106070.c test [PR106070]

Browse source 
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.

	PR tree-optimization/106070
	* gcc.dg/torture/pr106070.c: Use unsigned long long instead of
	unsigned long and -1ULL instead of 0xffffffffffffffff, deobcuscate
	and improve formatting.
