libunwindstack: don't save pseudoregisters while evaluating Dwarf
Currently, while evaluating a Dwarf section, even pseudoregisters are
saved in regs_info. Since pseudoregisters are stored separately from
ordinary registers, trying to read them the usual way will result in
an out-of-bounds read. There's no memory corruption as regs_info is
big enough to store all existing pseudoregisters.
With this patch, pseudoregisters are simply not saved in regs_info.
Added new unit tests to cover the pseudo register cases.
Test: libunwindstack_test
