py: Move constant folding from compiler to parser.
...
It makes much more sense to do constant folding in the parser while the
parse tree is being built. This eliminates the need to create parse
nodes that will just be folded away. The code is slightly simpler and a
bit smaller as well.
Constant folding now has a configuration option,
MICROPY_COMP_CONST_FOLDING, which is enabled by default.

py/objarray: Allow to create array of void pointers, as extension to CPython.
...
Using 'P' format specifier (matches struct module). This is another shortcut
for FFI, just as previously introduced "array of objects" ('O').

py: Don't generate unnecessary parse nodes for assignment or kwargs.

This patch eliminates the need for a nested parse node for assignments
and keyword arguments. It saves a little bit of RAM when parsing.

py: Allocate parse nodes in chunks to reduce fragmentation and RAM use.
...
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.

py/mpz: Force rhs of mpz_shl_inpl/mpz_shr_inpl to be unsigned.
...
Python semantics are that rhs of shift must be non-negative, so there's
no need to handle negative values in the underlying mpz implementation.

py/parsenum: Provide detailed error for int parsing with escaped bytes.
...
This patch adds more fine grained error message control for errors when
parsing integers (now has terse, normal and detailed). When detailed is
enabled, the error now escapes bytes when printing them so they can be
more easily seen.
