start with a cv-qualifier. DeclaratorDecl::getTypeSpecStartLoc() does not
produce the location of the first type-specifier (the cv-qualifier) in this
case, because we don't track source locations for cv-qualifiers.

No test here: I've not found a way to test this with a lit-style test, and
introducing a gtest test for this seems unwarranted. Suggestions welcome!

pointer, but such folding encounters side-effects, ignore the side-effects
rather than performing them at runtime: CodeGen generates wrong code for
__builtin_object_size in that case.

The RegisterInfo descriptors for the convenience registers can specify an offset to be added to the offset as derived from
the value_regs field, which is useful for future expansion purposes.  As of now, we have:

    calculated_offset_of_eax = offset_of_rax + (offset_of_eax_from_the_descriptor which is 0)

After a lot of discussion, we realized it's not the best option for run-time bounds checking

Also make sure registers aren't erased twice if the dead def mentions
the register twice.

This fixes PR12911.
