0ff50d49d1 OpenCL: Improve vector printf warnings 
The vector modifier is considered separate, so
don't treat it as a conversion specifier.

This is still not warning on some cases, like
using a type that isn't a valid vector element.

Fixes bug 39652

314fbfa1c4 Reapply Logging: make os_log buffer size an integer constant expression. 
The size of an os_log buffer is known at any stage of compilation, so making it
a constant expression means that the common idiom of declaring a buffer for it
won't result in a VLA. That allows the compiler to skip saving and restoring
the stack pointer around such buffers.

This also moves the OSLog and other FormatString helpers from
libclangAnalysis to libclangAST to avoid a circular dependency.
