Subject: [PATCH] [clang][test] Improve unit tests for Fixed point AST
matchers.
We have AST matchers for fixed point float numbers since commits
789215dc0db174c9fdd273436fdd60d8289a9fc0 and
ff9120636e9c890b4db735d252d16b92091dde55. However in those commits
the unit tests were not added. Amending the test suit.
