Added tests to _testingUtils.c (currently failing due to a bug in printing 64bit numbers)
Fixing this bug will expose a failing test case for Concrete/ConstantExpr.ll
Fixed test/Concrete/ConstantExpr.ll

The difference between a 64bit pointer truncated to 32 bits and the
original 64bit pointer would never be 0 if any of the high 32bits in
the pointer were test. If lli and klee had a different value for the
top 32bits of the address this test would be marked as failing.

Due to the 64bit printing buf in _testingUtils this was not exposed before.

The fix clears the top 32bits of the difference.
Fix the bug in printing 64bit numbers, set the test to expect passing. Changed _testingUtils to use stdint.h
Fixed declaration of print_int that Travis complained about
Switch to using autoconf 2.69 this version is more commonly available
on Linux systems (2.60 is quite old) which will make updating the
configure script easier for most users.

configure: allow stp being installed in /

I have stp in standard paths: /usr/include and /usr/lib64. Allow that
by correct STP_CFLAGS + STP_LDFLAGS instead of STP_ROOT. Those are
empty when --with-stp is not passed.

configure is regenerated by autoconf too.

Upstream libstp is no longer dependent on Boost so remove the
configure/Makefile code that adds Boost as a depdendency because We
don't need to support old versions of STP that needed Boost.

Executor: do not crash on non-sized globals

Sometimes, globals are not sized and ->getTypeStoreSize on such type
crashes inside the LLVM. Check whether type is sized prior to calling
the function above.
