Newer compilers use `-std=gnu17` as the default when compiling C code.
Fix all the test cases that violate this behaviour or explicitly request
older standards `-std=c89` where necessary.

Otherwise optimizations done in klee won't have any effect.

As we do not support LLVM 2.9 anymore, we can use FileCheck LINE instead of hard coding line numbers.

parallel.
- It would be nice if there was an easier way to do this that didn't involve
editing all of the tests (like running each test in its own directory), but
this approach fixes #146 and doesn't involve changing 'lit' or writing a
wrapper harness. My assumption is a lot of tests start are derived from
another one, so hopefully following this convention won't be burdensome, and
I updated 'make check' so that it will produce an error if any test runs klee
without --output-dir (by checking for the existing of klee-last files).
- This also helps with #147 but I still can't fully run tests in parallel (I
start hitting STP errors).

a file created by KLEE exists. A big difference between
DejaGNU and llvm-lit is that in DejaGNU the working directory
is the test output directory (e.g. test/Feature/Output) but
in llvm-lit the working directory is the test directory
(e.g. test/Feature )
To fix this I have used the %T substitution variable for llvm-lit.
I have also improved some tests by using LLVM's FileCheck tool
and removing of hard coded constants for data type size in
some places.
This commit inevitably breaks running the tests under DejaGNU.
Although it is possible to hack by introducing the %T substitution
variable some tests would still be broken because the use of shell
pipes in DejaGNU doesn't seem to work properly. I could work around
this but it's really not worth the effort.

- Lots more tweaks, documentation, and web page content is needed,
but this should compile & work on OS X & Linux.
