[PATCH] D28954: [analyzer] Add support for symbolic float expressions

[Dominic Chen via Phabricator via cfe-commits]

ddcc created this revision.
Herald added a subscriber: mgorny.

With the Z3 constraint manager, symbolic floating-point constraints can also be reasoned about. This commit includes a basic floating-point checker for domain errors with math functions.
