Update to the latest macaw
...
In macaw core, the type of the arch-specific 'disassemble' function changed to
no longer take a Memory, and to pass the maximum offset as an Int instead of a
MemWord. It also removed the jump table entry size (which is no longer
required).
The removal of the Memory parameter required a bit of a change in how the
instruction parsers are structured, but it isn't a huge change (the "memory
contents after an address" can be computed from a MemSegmentOff, too).

Improve the TH generator for instruction matchers (i.e., execInstruction)
...
The previous generator put all of the code for each matcher in a single large
case expression. While there were individual functions broken out for each case
body, they were all still in the same let expression, which created a huge term.
This refactoring lifts all of the semantics definition bodies to the top
level (with NOINLINE pragmas) to give the code generator less to chew on at a
time.
This improves compile times a little, but, more importantly, works around a bug
in the register allocator in GHC 8.4 that caused a crash in the PowerPC
semantics functions.

[arm] Implement identifyReturn (not properly functional).
...
The Macaw Discovery now calls the identifyReturn to identify return
statements. Supply this for ARM, but at present this simply
replicates the original inline code which does not properly detect ARM
return operations because the low bit(s) of the address are always
cleared when writing to the instruction pointer in ARM.
