Fixed code that caused a seg-fault after parsing a (deferred) post-count argument followed by a (nested) function-call argument.
...
The old broken code defers the count until the end of the (parent function's) argument list. But, a nested function call clears the pointer to the deferred type. That leads to an access violation.
The new code defers only until the end of each argument. Fixes #1320 .

Adjust type of int constants that fit in char
...
When there is an integral constant like `3` in an expression, it has
type `int` according to the C spec, even though it can be represented
as an `unsigned char`. Change codegen (`hie_internal` and `typeadjust`)
to treat it as `unsigned char` instead of `int` so that faster,
unsigned operations can be used.
For the test case in #1298 , reduces the cycles per iteration from
4311 to 1884. This is a great improvement, but still much worse than
the 1053 cycles/iter from `c4698df~`, so more work remains to be done.
Further partial fix for #1298 and #1308 .

Changed codegen for postfix inc/dec operations by deferring them till sequence points.

This usually allows faster & smaller code.
