dollops not created or placed for some WRT instructions
Observed with the zestcfi_function_entry relocation, which is placed on a scoop. In both the dollop manager and zipr, it appears that handling of WRT insns only addresses relocations placed on instructions, not scoops. I tried a naïve solution of iterating over all relocations in m_firp->getRelocations(), and this did ensure that the zestcfi entry instruction was put into the placement queue. However, my test program transformed with cfi was still segfaulting. What are your thoughts about handling this @jdh8d ?
Here is a link to my naïve solution: https://git.zephyr-software.com/allzp/zipr/tree/WRT_fix_experimental
My knowledge of zipr's inner workings is...far from comprehensive so there could easily be a silly mistake in the above.
