It turns out not to be necessary. Russ expressed a preference for
avoiding module fetches over making 'go mod tidy' work within std and
cmd right away, so for now we will make the loader use the vendor
directory for the standard library even if '-mod=vendor' is not set
explicitly.

Two funcs and a field were unused. Remove them.
A few statements could be made simpler.
importsym's pos parameter was unused, so remove it.
Finally, don't use printf-like funcs with constant strings that have no
formatting directives.

TestEmptyDwarfRanges has been added in CL 94816.
This test is failing on Plan 9 because executables
don't have a DWARF symbol table.

Variables captured by a closure were always assigned to the root scope
in their declaration function. Using decl.Name.Defn.Pos will result in
the correct scope for both the declaration function and the capturing
function.

When a local variable is moved to the heap the declaration position
should be preserved so that later on we can assign it to the correct
DW_TAG_lexical_block.

Change compiler and linker to emit DWARF lexical blocks in .debug_info
section when compiling with -N -l.
Version of debug_info is updated from DWARF v2 to DWARF v3 since
version 2 does not allow lexical blocks with discontinuous PC ranges.
Remaining open problems:
- scope information is removed from inlined functions
- variables records do not have DW_AT_start_scope attributes so a
variable will shadow other variables with the same name as soon as its
containing scope begins, even before its declaration.
Updates #6913.
