gdb: New API for tracking innermost block
This commit is preparation for a later change, at this point there
should be no user visible change.
We currently maintain a global innermost_block which tracks the most
inner block encountered when parsing an expression.
This commit wraps the innermost_block into a new class, and switches all
direct accesses to the variable to use the class API.
gdb/ChangeLog:
* ada-exp.y (write_var_from_sym): Switch to innermost_block API.
* ada-lang.c (resolve_subexp): Likewise.
* breakpoint.c (set_breakpoint_condition) Likewise.
(watch_command_1) Likewise.
* c-exp.y (variable): Likewise.
* d-exp.y (PrimaryExpression): Likewise.
* f-exp.y (variable): Likewise.
* go-exp.y (variable): Likewise.
* m2-exp.y (variable): Likewise.
* objfiles.c (objfile::~objfile): Likewise.
* p-exp.y (variable): Likewise.
* parse.c (innermost_block): Change type.
* parser-defs.h (class innermost_block_tracker): New.
(innermost_block): Change to innermost_block_tracker.
* printcmd.c (display_command): Switch to innermost_block API.
(do_one_display): Likewise.
* rust-exp.y (do_one_display): Likewise.
* symfile.c (clear_symtab_users): Likewise.
* varobj.c (varobj_create): Switch to innermost_block API, replace
use of innermost_block with block stored on varobj object.
