Makefiles: Remove duplicate object files when linking.
...
Scenario: module1 depends on some common file from lib/, so specifies it
in its SRC_MOD, and the same situation with module2, then common file
from lib/ eventually ends up listed twice in $(OBJ), which leads to link
errors.
Make is equipped to deal with such situation easily, quoting the manual:
"The value of $^ omits duplicate prerequisites, while $+ retains them and
preserves their order." So, just use $^ consistently in all link targets.

py: With obj repr "C", change raw str accessor from macro to function.
...
This saves around 1000 bytes (Thumb2 arch) because in repr "C" it is
costly to check and extract a qstr. So making such check/extract a
function instead of a macro saves lots of code space.

py: Add object repr "C", where 30-bit floats are stuffed in obj word.
...
This new object representation puts floats into the object word instead
of on the heap, at the expense of reducing their precision to 30 bits.
It only makes sense when the word size is 32-bits.

Generally, ports should inherit INC from py.mk, append to it, not
overwrite it. TODO: Likely should do the same for other vars too.

unix/modtime: Implement ticks_ms(), ticks_us() and ticks_diff().

All of these functions return positive small int, thus range is 2 bits less
than word size (30 bit on 32-bit systems, 62 bit on 64-bit systems).

py: Add option for inline assembler to support ARMv7-M instructions.
...
Cortex-M0, M0+ and M1 only have ARMv6-M Thumb/Thumb2 instructions. M3,
M4 and M7 have a superset of these, named ARMv7-M. This patch adds a
config option to enable support of the superset of instructions.

The whole current port gets slurped into a static lib named
"libmicropython.a". Maybe that's not ideal, but at least something
to start with.

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: 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.
