Josef Weidendorfer 2fd31d27a2 Callgrind: use jmpkind from VEX for side exits.

To detect calls and returns, Callgrind's heuristic
starts with using the jumpkind got from VEX for
a control flow change instruction. However, for
side exits, it always assumed a (conditional) jump,
which holds true for x86, but e.g. not for ARM.

This fixes Callgrind to use the jumpkind found
by VEX for all exits, which should help making
Callgrind work for ARM. It also moves the check
whether a boring jump is actually a fall-through
to instrumentation time. This changes (fixes) the
result for indirect jumps to the next instruction,
which should not be classified as fall-through
(anyway, this case is probably very rare).

This patch introduces an own enum for jump kinds
in Callgrind. This is less confusing than misusing
the VEX jump kind type, as Callgrinds wants
to distinguish BB fall-throughs from real jumps
(which both are Ijk_Boring in VEX).
Also, setup_bbcc now stores separately whether the
jump kind is conditional or not.
