Fix location of sizeof/alignof (PR c++/80016)

PR c++/80016 reports an issue with bizarre underlined range
for a complicated expression.

The root cause for the incorrect *starting* location of that range
is that alignof and sizeof expressions currently have
start == finish == caret at the opening parenthesis of the
expression.

This patch fixes this by generating appropriate start and finish
locations for alignof and sizeof expressions.

libiberty: Limit demangler maximum d_print_comp recursion call depth.

The fix for PR demangler/70909 and 67264 (endless demangler recursion)
catches when a demangle_component is printed in a cycle. But that doesn't
protect the call stack blowing up from non-cyclic nested types printed
recursively through d_print_comp. This can happen by a (very) long mangled
string that simply creates a very deep pointer or qualifier chain. Limit
the recursive d_print_comp call depth for a d_print_info to 1K nested
types.

libiberty/ChangeLog:

        * cp-demangle.c (MAX_RECURSION_COUNT): New constant.
        (struct d_print_info): Add recursion field.

is handled in the same way.

libiberty: Don't update and remove did_subs field from demangler structs.

size. It was no longer used when the malloc-less callback interface
was introduced in 2007 (svn r121305). But the field was still updated.
When backtracking was introduced in 2013 (svn r205292) did_subs was
also added to the d_info_checkpoint struct. But except for updating
the field it was still not used.

Since it is never used just stop updating the field and remove it
from the two structs.
