Remove purespace and ancillary codescratch/no-purespace-old

Now that purespace is not used any more, remove it, along with the functions
used to allocate into it.  Use equivalent functions allocating into the
normal heap.
Remove calls to PURE_P since they always return false.

(pure, purebeg, pure_size, pure_bytes_used_before_overflow)

(pointer_align): Move after definition of USE_ALIGNED_ALLOC and only
define it if USE_ALIGNED_ALLOC is not used.

`make_hash_table`.

symbol names.
