Remove redundant code in the compiler.

Browse source 
During instruction translation (linked list -> iseq generation), we can
treat `TS_VALUE` and `TS_ISEQ` the same as they are just embedded in the
generated sequences.  The only difference between `TS_ISE` and `TS_IC`
is that an inline storage entry may contain a markable `VALUE` pointer
at some point, so we need to flag the iseq as containing markable
objects.
