Patch from Argiris Kirtzidis.

The patch fixes some debug assertions that the msvcrt throws:

1)
-    if (isprint(value) && value < 256) {
+    if (value < 256 && isprint(value)) {

isprint() does an assertion check of its own for value < 256; check value before calling it to prevent it.


2)
-    Stmt->Names.push_back(std::string(&data[0], data.size()));
+    if (data.size() == 0)
+      Stmt->Names.push_back(std::string());
+    else
+      Stmt->Names.push_back(std::string(&data[0], data.size()));

If data.size() == 0 then data[0] throws "out of range" assertion.

Really really bad local register allocator bug. On X86, it was never using ESI, EDI, and EBP because of a bug in RALocal::isPhysRegAvailable(). For example, when
it checks if ESI is available, it then looks at registers aliases to ESI. SIL is marked -2 (not allocatable) but isPhysRegAvailable() incorrectly assumes it is in use and returns false for ESI.

instead of with mmx registers.  This horribleness is apparently
done by gcc to avoid having to insert emms in places that really 
should have it.  This is the second half of rdar://5741668.
