This PR is a general cleanup for garbage collection and memory
allocation code paths.
Changes:
* Removed an unnecesary local variable from 'ecma_gc_mark'.
* Refactored 'ecma_gc_run' to have an implicit list head during
iteration, which results in one less condition in the loops,
and changed the loops to use compressed pointers to reduce the
overall amount of compression/decompression.
* Renamed 'jmem_free_unused_memory_severity_t' to 'jmem_pressure_t',
and added additional values.
* Removed 'jmem_free_unused_memory_callback', instead
'ecma_free_unused_memory' is now called directly.
* Reworked 'ecma_free_unused_memory' to handle all code paths related
to 'jmem_pressure_t', and moved all relevant code paths into this
function. This simplifies the code paths in other places.
* Reworked 'jmem_heap_gc_and_alloc_block' to be more streamlined.
* Changed mem-stats to not report unused pool chunks as allocated
memory.
* Created an allocator internal API for allocating/freeing memory blocks
that are not reported as used memory in mem-stats.
* Removed iteration statistics for the jerry allocator from mem-stats,
as they don't provide any actually useful information.
