[PATCH 0/4] Fix bug in value_subscript when range's high bound is not known

[Simon Marchi]

This series fixes PR26875 and PR26901.  Since this is a regression
introduced in GDB 10, I would consider this for the GDB 10 stable
branch.

Simon Marchi (4):
  gdb: make discrete_position return optional
  gdb: make get_discrete_bounds return bool
  gdb: split get_discrete_bounds in two
  gdb: fix value_subscript when array upper bound is not known
