Overshift is where a Shl, AShr or LShr has a shift width greater
than the bit width of the first operand. This is undefined behaviour
in LLVM so we report this as an error.

even if there were many divide by zero bugs.

The fix basically inlines all function calls to klee_div_zero_check()
so that each call to klee_report_error() is a unique instruction
for each instrumentation of a divide operation.

It also seems that inlining the call "magically" fixed the debug information
(file and line number) of the instruction so that the debug information on the
inlined instructions matches that of the instrumented division instruction.

Note that the command line option -emit-all-errors could be used to
workaround the bug fixed in this commit.

The Default is Release+Asserts but if you are building KLEE with debug symbols (for example
"Release+Debug+Asserts" or "Debug+Asserts") then this breaks because KLEE will
look for the bitcode libraries in the wrong place because the
RUNTIME_CONFIGURATION macro is not defined to be what KLEE actually builds as.

This has been tweaked so that when we build the bitcode libraries the Makefile
variable "DEBUG_SYMBOLS" is correctly overridden.

can now be logged in SMT-LIBv2 format as well as KQuery format. The
names of logging files has changed and also KLEE now informs users
which files are being written to.

The Default is Release+Asserts but if you are building for example "Release+Debug+Asserts" then this break because
KLEE will look for the bitcode libraries in the wrong place because the RUNTIME_CONFIGURATION macro is not defined
to be what KLEE actually builds as.

This has been tweaked so that when we build the bitcode libraries as "Release+Asserts" whether or not we've
choosen debug for the main build of KLEE does not matter.

This was due to ConstantExpr being replaced with IConstantExpr (see commit 04779d19).
Later on this changed back to ConstantExpr (se commit 8bfde3a7)

"1. At configure time the --with-stp= option is now mandatory.
 2. The HAVE_EXT_STP macro has been removed.
