Cut down from a failure in core.cpuid. With all of the build problems with
druntime at the moment I'm not able to get any normal file to build on 64bits;
but this is the relevant case from the runtime build. This probably needs -O
-release, since it goes away if I replace 'while' with 'if'; but I haven't
checked which flags are actually necessary.

=============
__gshared char[48] dish;
void foo()
{
 int end = 0;
 while (dish[$-end-1]==0) { ++end; }
}
===========
src/core/cpuid.d:(.text._D4core5cpuid3fooFZv+0x9): relocation truncated to fit:
R_X86_64_PC32 against symbol `_D4core5cpuid4dishG48a' defined in .data section
in obj/core/cpuid.o
