Refactor the ELFRelocationEntry (pull up) and move the arch-specific statics to inside the class where it belongs.

Next step is to rationally break apart the RecordRelocation()

Probably the step will be to have 1 member function for ech slot of the ELFRelocationEntry()

state. Previously Thumb2 would restore sp from fp like this:
mov sp, r7
sub, sp, #4
If an interrupt is taken after the 'mov' but before the 'sub', callee-saved
registers might be clobbered by the interrupt handler. Instead, try
restoring directly from sp:
add sp, #4
Or, if necessary (with VLA, etc.) use a scratch register to compute sp and
then restore it:
sub.w r4, r7, #8
mov sp, r7
