25b0fbd679 Don't use clock_gettime on macOS 
This commit stops using the monotonic clock API on macOS because it is 
supported only on macOS >= 10.12. Instead, it uses the fallback clock 
APIs for platforms without monotonic clock support.

The use of `clock_gettime` was causing issues on Atom because, even 
though we build it on a new macOS version supporting such API, some 
users may run Atom on older versions of macOS. On those platforms, Atom 
would crash whenever opening a file parsed with a tree-sitter grammar.

6e2a60629c Make ts_tree_delete and ts_parser_delete NULL-safe. 
Historically, `free(3)`-style functions have been NULL-safe, to make
resource handling functions more robust. This doesn't seem to be the
case with tree-sitter's `ts_tree_delete` and `ts_parser_delete` C
functions, which immediately dereference the passed pointer. This
leads to complexity in client libraries that have to ensure that trees
and parsers are cleaned up correctly.

This patch adds NULL checks to `parse_delete` and `tree_delete`. They
should have negligable performance impacts, since null checks are fast.

I didn't change the internal _delete functions, as arguably those
being NULL-unsafe is a feature, not a bug.

006a931ab8 Tests: Prevent array reallocations during ts_stack_print_dot_graph 
When debugging a test with 'script/test -D', the DOT-graph generation
code was sometimes causing reallocations that were not captured by the
allocation tracker, because we explicitly disable allocation-tracking
for that method in order to reduce noise when debugging memory leaks.

By growing the relevant array *prior* to turning off allocation
tracking, we can ensure that it is not reallocated within that function,
avoiding false positive memory leak errors.

Fixes #302

This allows you to assert about fields in tests. But if your test 
s-expression does *not* include fields, the fields will be stripped from
