ba707cadae Add block::function_block 
This adds the method block::function_block, to easily access a block's
enclosing function block.

b7a92724c5 Simplify block_find_symbol 
block_find_symbol takes a callback function, but only two callbacks
are ever passed to it -- and they are similar enough that it seems
cleaner to just have block_find_symbol do the work itself.  Also,
block_find_symbol can take a lookup_name_info as an argument,
following the general idea of pushing the construction of these
objects as high in the call chain as feasible.

Regression tested on x86-64 Fedora 38.

911e1e795e Add symbol::matches method 
This adds symbol::matches, a wrapper for symbol_matches_domain.  Most
places calling symbol_matches_domain can call this method instead,
which is a bit less wordy and also (IMO) clearer.

0688bf443c Store 'name' in block_iterator 
This changes the block_iterator to store the 'name' that is used by
block_iter_match_next.  This avoids any problem where the name could
be passed inconsistently, and also makes the subsequent patches easier
to understand.

dda83cd783 gdb, gdbserver, gdbsupport: fix leading space vs tabs issues 
Many spots incorrectly use only spaces for indentation (for example,
there are a lot of spots in ada-lang.c).  I've always found it awkward
when I needed to edit one of these spots: do I keep the original wrong
indentation, or do I fix it?  What if the lines around it are also
wrong, do I fix them too?  I probably don't want to fix them in the same
patch, to avoid adding noise to my patch.

So I propose to fix as much as possible once and for all (hopefully).

One typical counter argument for this is that it makes code archeology
more difficult, because git-blame will show this commit as the last
change for these lines.  My counter counter argument is: when
git-blaming, you often need to do "blame the file at the parent commit"
anyway, to go past some other refactor that touched the line you are
interested in, but is not the change you are looking for.  So you
already need a somewhat efficient way to do this.

Using some interactive tool, rather than plain git-blame, makes this
trivial.  For example, I use "tig blame <file>", where going back past
the commit that changed the currently selected line is one keystroke.
It looks like Magit in Emacs does it too (though I've never used it).
Web viewers of Github and Gitlab do it too.  My point is that it won't
really make archeology more difficult.

The other typical counter argument is that it will cause conflicts with
existing patches.  That's true... but it's a one time cost, and those
are not conflicts that are difficult to resolve.  I have also tried "git
rebase --ignore-whitespace", it seems to work well.  Although that will
re-introduce the faulty indentation, so one needs to take care of fixing
the indentation in the patch after that (which is easy).

It's possible that the trigger patch breaks an undocumented invariant:  I've
tried a build and test run without the trigger patch and did not manage to
trigger the assert.

For robustness-sake, fix the assert by bailing out if 'BLOCK_START (b) <= pc'
doesn't hold.

Tested on x86_64-linux.

de82891ce5 [gdb/symtab] Prefer def over decl (inter-CU case) 
When running test-case gdb.threads/tls.exp with target board -readnow, we
have:
...
(gdb) print a_thread_local^M
Cannot find thread-local storage for process 0, executable file tls/tls:^M
Cannot find thread-local variables on this target^M
(gdb) FAIL: gdb.threads/tls.exp: print a_thread_local
...
while with native we have:
...
(gdb) print a_thread_local^M
Cannot read `a_thread_local' without registers^M
(gdb) PASS: gdb.threads/tls.exp: print a_thread_local
...

The difference in behaviour can be explained as follows.  Without -readnow, we
have two a_thread_locals, the def and the decl, each in a different CU:
...
$ gdb -batch outputs/gdb.threads/tls/tls \
    -ex "maint expand-symtabs" \
    -ex "print a_thread_local" \
    -ex "maint print symbols" \
    | grep "a_thread_local;"
Cannot read `a_thread_local' without registers
 int a_thread_local; computed at runtime
 int a_thread_local; unresolved
...
and with -readnow, we have the opposite order:
...
$ gdb -readnow -batch outputs/gdb.threads/tls/tls  \
    -ex "maint expand-symtabs" \
    -ex "print a_thread_local" \
    -ex "maint print symbols" \
    | grep "a_thread_local;"
Cannot find thread-local storage for process 0, executable file tls/tls:
Cannot find thread-local variables on this target
 int a_thread_local; unresolved
 int a_thread_local; computed at runtime
...

Fix the FAIL by preferring the def over the decl (something we already do
intra-CU since the fix for PR24971, commit 93e55f0a03 "[gdb/symtab] Prefer var
def over decl").

Build and reg-tested on x86_64-linux.

08feed99cb Change get_objfile_arch to a method on objfile 
This changes get_objfile_arch to be a new inline method,
objfile::arch.

To my surprise, this function came up while profiling DWARF psymbol
reading.  Making this change improved performance from 1.986 seconds
to 1.869 seconds.  Both measurements were done by taking the mean of
10 runs on a fixed copy of the gdb executable.
