tcg: Add TCGV_UNUSED_PTR, TCGV_IS_UNUSED_PTR, TCGV_EQUAL_PTR

We have macros for marking TCGv values as unused, checking if they
are unused and comparing them to each other. However these only exist
for TCGv_i32 and TCGv_i64; add them for TCGv_ptr as well....

tcg: Use bitmaps for free temporaries

We previously allocated 32-bits per temp for the next_free_temp entry.
We now allocate 4 bits per temp across the 4 bitmaps.

Using a linked list meant that if a translator is tweeked, resulting in
temps being freed in a different order, that would have follow-on effects...
