static __global int Var = 0;

In this case Var is a non premptable symbol and so its address can be used as the value of Ptr, with a base relative relocation that will add the delta between the ELF address and the actual load address. Such relocations do not require a symbol.
This also fixes LLD which was incorrectly generating a PCREL64 for this case.

This is in preparation for my next change, which will introduce a relro
nobits section. That requires that relro sections appear at the end of the
progbits part of the r/w segment so that the relro nobits section can appear
contiguously.
Because of the amount of churn required in the test suite, I'm making this
change separately.

This is needed for the following case (OpenCL example):
__global int Var = 0;
__global int* Ptr[] = {&Var};
