Summary:
Sledge does not terminate on programs with recursion, because
functions get "infinitely inlined" and therefore recursion is not
treated as retreating edge.
This patch bounds the number of times the same function can "inlined"
to respect the bound (`-b` option). On each call we check the number of
occurances of the called function in the call stack. If that is higher
than the bound, we skip it.

Summary:
This diff changes the translation of global variables to translate the
initializer whenever it exists in LLVM, rather than relying on
linkage. Previously code such as
```
char *mutable_string = "hahaha";
```
would lead to LLVM code
```
nutritious_string = global i8* getelementptr inbounds ([7 x i8], [7 x i8]* @.str, i32 0, i32 0), align 8, !dbg !0 ; [#uses=2 type=i8**]
```
in which `mutable_string` had `External` linkage according to
`Llvm.linkage` even though it has an initializer. This could cause
sledge to drop the initializer.

Summary:
Make could get confused and use both the $(MODEL_DIR)/cxxabi.bc and
%.bc rules, leading to build failure.
