compiler, runtime: copy slice code from Go 1.7 runtime
Change the compiler handle append as the gc compiler does: call a
function to grow the slice, but otherwise assign the new elements
directly to the final slice.
For the current gccgo memory allocator the slice code has to call
runtime_newarray, not mallocgc directly, so that the allocator sets the
TypeInfo_Array bit in the type pointer.
Rename the static function cnew to runtime_docnew, so that the stack
trace ignores it when ignoring runtime functions. This was needed to
fix the runtime/pprof tests on 386.

combine: Improve change_zero_ext (fixes PR71847)
This improves a few things in change_zero_ext. Firstly, it should use
the passed in pattern in recog_for_combine, not the pattern of the insn
(they are not the same if the whole pattern was replaced). Secondly,
it handled zero_ext of a subreg, but with hard registers we do not get
a subreg, instead the mode of the reg is changed. So this handles that.
Thirdly, after changing a zero_ext to an AND, the resulting RTL may become
non-canonical, like (ior (ashift ..) (and ..)); the AND should be first,
it is commutative. And lastly, zero_extract as a set_dest wasn't handled
at all, but now it is.
This fixes the testcase in PR71847, and improves code generation in some
other edge cases too.

The problem in that PR:
We have two insns, in this order:
(insn/f 300 299 267 8 (set (reg:DI 65 lr)
(reg:DI 0 0)) 579 {*movdi_internal64}
(expr_list:REG_DEAD (reg:DI 0 0)

and sched swaps them (when compiling for power6, it tries to put memory
stores together, so insn 310 is moved up past 300 to go together with
some other store). But the REG_CFA_RESTORE and REG_CFA_OFFSET cannot be
swapped (they both say where the orig value of LR now lives).

Fix the leak by freeing the file->path in destroy_cpp_file.
However, doing so would lead to a use-after-free in input.c's file cache
since the filenames in this cache are the libcpp file->path buffers.
Hence we need to ensure that any references to the file in the input.c
cache are purged before cleaning up file->path. This is normally done
by the temp_source_file dtor. Hence we need to reorder things to that
the temp_source_file dtor runs before cleaning up the cpp_parser. The
patch does this by introducing a wrapper class around cpp_parser *, so
that the dtor can run after the dtor for temp_source_file.

* input.c (fcache::file_patch): Add comment about lifetime.
(selftest::cpp_reader_ptr): New class.
(selftest::lexer_test): Convert m_parser from cpp_reader *
to a cpp_reader_ptr, and move m_tempfile to after it.

Implement ~line_maps ()
line_maps instances such as the global line_table are
GC-managed, but the htab within location_adhoc_data_map.htab
is not GC-managed.
Previously this was deleted manually by a call to
location_adhoc_data_fini within toplev::main.
However, on adding a call to forcibly_ggc_collect after the
selftests, all of the htabs for the various line_tables
created during the selftests start showing up as leaks

adding a destructor to class line_maps, which cleans up
the non-GC-managed htab.
