773278ec30 py/lexer: Simplify handling of line-continuation error. 
Previous to this patch there was an explicit check for errors with line
continuation (where backslash was not immediately followed by a newline).

But this check is not necessary: if there is an error then the remaining
logic of the tokeniser will reject the backslash and correctly produce a
syntax error.

ae43679792 py/lexer: Use strcmp to make keyword searching more efficient. 
Since the table of keywords is sorted, we can use strcmp to do the search
and stop part way through the search if the comparison is less-than.

Because all tokens that are names are subject to this search, this
optimisation will improve the overall speed of the lexer when processing
a script.

The change also decreases code size by a little bit because we now use
strcmp instead of the custom str_strn_equal function.

a68c754688 py/lexer: Move check for keyword to name-tokenising block. 
Keywords only needs to be searched for if the token is a MP_TOKEN_NAME, so
we can move the seach to the part of the code that does the tokenising for
MP_TOKEN_NAME.

71019ae4f5 py/grammar: Group no-compile grammar rules together to shrink tables. 
Grammar rules have 2 variants: ones that are attached to a specific
compile function which is called to compile that grammar node, and ones
that don't have a compile function and are instead just inspected to see
what form they take.

In the compiler there is a table of all grammar rules, with each entry
having a pointer to the associated compile function.  Those rules with no
compile function have a null pointer.  There are 120 such rules, so that's
120 words of essentially wasted code space.

By grouping together the compile vs no-compile rules we can put all the
no-compile rules at the end of the list of rules, and then we don't need
to store the null pointers.  We just have a truncated table and it's
guaranteed that when indexing this table we only index the first half,
the half with populated pointers.

This patch implements such a grouping by having a specific macro for the
compile vs no-compile grammar rules (DEF_RULE vs DEF_RULE_NC).  It saves
around 460 bytes of code on 32-bit archs.

e6003f466e py: De-optimise some uses of mp_getiter, so they don't use the C stack. 
In these cases the heap is anyway used to create a new object so no real
need to use the C stack for iterating.  It saves a few bytes of code size.

f4df3aaa72 py: Allow bytecode/native to put iter_buf on stack for simple for loops.

ae8d867586 py: Add iter_buf to getiter type method. 
Allows to iterate over the following without allocating on the heap:
- tuple
- list
- string, bytes
- bytearray, array
- dict (not dict.keys, dict.values, dict.items)
- set, frozenset

Allows to call the following without heap memory:
- all, any, min, max, sum

TODO: still need to allocate stack memory in bytecode for iter_buf.
