bug#39180: 27.0.50; [PATCH] Use expressions as memory location in gdb-mi memory buffer

[Yuan Fu]

Currently gdb-mi does allow expressions as memory address, but it translates it 
to a fixed address. This patch makes gdb to store the expression and 
re-evaluate on updates. So the address changes as expression’s value changes.
