Fix regression in Ada aggregate assignment
A recent upstream patch of mine caused a regression in aggregate assignment. The bug was that add_component_interval didn't properly update the array contents in one resize case. I found furthermore that there was no test case that would provoke this failure. This patch fixes the bug and introduces a test. gdb/ChangeLog 2021-01-07 Tom Tromey <tromey@adacore.com> * ada-lang.c (add_component_interval): Start loop using vector's updated size. gdb/testsuite/ChangeLog 2021-01-07 Tom Tromey <tromey@adacore.com> * gdb.ada/assign_arr.exp: Add 'others' test.
