Diana Picus b67264b182 [ARM] GlobalISel: More tests. NFC.
Test constants as well in the PIC tests. These are also represented as
G_GLOBAL_VALUE, and although they are treated just like other globals
for PIC, they won't be for ROPI, so it's good to have this coverage.

Diana Picus c9f29c62cc [ARM] GlobalISel: Select globals in PIC mode
Support the selection of G_GLOBAL_VALUE in the PIC relocation model. For
simplicity we use the same pseudoinstructions for both Darwin and ELF:
(MOV|LDRLIT)_ga_pcrel(_ldr).

This is new for ELF, so it requires a small update to the ARM pseudo
expansion pass to make sure it adds the correct constant pool modifier
and add-current-address in the case of ELF.
