[PATCH v3 0/7] Remove addrmap from blockvector

[Jan Vrany <jan@vrany.io>]

This is a v3 of an earlier series removing the addrmap from blockvector, a
step towards expandable blockvectors which are needed for lazy CU expansion
and forPython JIT API.

Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=33829

* v1 submission is here:

  https://inbox.sourceware.org/gdb-patches/20260219185638.360694-1-jan.vrany@labware.com/

* v2 submission is here:

  https://inbox.sourceware.org/gdb-patches/20260304165914.3209106-1-jan.vrany@labware.com/

* changes since v3:

  * rebased on current master to accomodate changes in expanded_symbols_functions

  * re-tested on Linux x86_64 both with and without -readnow. I have spotted
    no regressions, but I need to say that on my machine and with my test
    setup a lot of tests fail with -readnow.

Thanks!

Jan
