Chandler Carruth d46f580986 [CFG Printer] Add support for writing the dot files with a custom
prefix.

Use this to direct these files to a specific location in the test suite
so that we don't write files out to random directories (or fail if the
working directory isn't writable).

Kristina Brooks 4f197cd736 Fix incorrect Twine usage in CFGPrinter
CFGPrinter (-view-cfg, -dot-cfg) invokes an undefined behaviour (dangling
pointer to rvalue) on IR files with branch weights. This patch fixes the
problem caused by Twine initialization and string conversion split into
two statements.

This change fixes the bug 37019. A similar patch to this problem was
provided in the llvmlite project

Patch by mcopik (Marcin Copik).
