OpenCL: Don't warn on v printf modifier

This avoids spurious warnings, but could use
a lot of work. For example the number of vector
elements is not verified, and the passed
value type is not checked.

Fixes bug 39486

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.
