Add returns_twice to functions that are known to return twice. This implements
...
the same behavior of gcc by keeping the attribute out of the function type.

Add security syntax checker for strcat() which causes the Static Analyzer to generate a warning any time the strcat() function is used with a note suggesting to use a function which provides bounded buffers. CWE-119.

Also, brings the security syntax checker more inline with coding standards.

Add abort() as a builtin. This has two effects: one, we warn for incorrect
...
declarations of abort(), and two, we mark it noreturn. Missing the latter
shows up in one of the "embarassing" tests (from the thread on llvmdev
"detailed comparison of generated code size for LLVM and other compilers").

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
...
- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
