<content type='text'>
With this patch parse nodes are allocated sequentially in chunks.  This
reduces fragmentation of the heap and prevents waste at the end of
individually allocated parse nodes.

Saves roughly 20% of RAM during parse stage.

<title>py: Remove mp_load_const_bytes and instead load precreated bytes object.</title>

Previous to this patch each time a bytes object was referenced a new
instance (with the same data) was created.  With this patch a single
bytes object is created in the compiler and is loaded directly at execute
time as a true constant (similar to loading bignum and float objects).
This saves on allocating RAM and means that bytes objects can now be
used when the memory manager is locked (eg in interrupts).

The MP_BC_LOAD_CONST_BYTES bytecode was removed as part of this.

Generated bytecode is slightly larger due to storing a pointer to the
bytes object instead of the qstr identifier.

Code size is reduced by about 60 bytes on Thumb2 architectures.

<title>py: Use a wrapper to explicitly check self argument of builtin methods.</title>

Previous to this patch a call such as list.append(1, 2) would lead to a
seg fault.  This is because list.append is a builtin method and the first
argument to such methods is always assumed to have the correct type.

Now, when a builtin method is extracted like this it is wrapped in a
checker object which checks the the type of the first argument before
calling the builtin function.

This feature is contrelled by MICROPY_BUILTIN_METHOD_CHECK_SELF_ARG and
is enabled by default.

See issue #1216.

Eg, builtin map can map over a map, etc, and call iternext deeply.

Addresses issue #1294.
