[NFC] Remove unused functions in ExecutionTest.cpp and assert.cpp (microsoft#7129) (microsoft#7132)

Some functions need to be removed / changed to unblock some internal
pipelines. They are emitting warnings that they are unused.
Specifically, `CompareOutputWithExpectedValueFloat`,
`CompareOutputWithExpectedValueHalf`, and
`CompareOutputWithExpectedValueFloat` need to be removed because they
are unused.
Additionally, there is a case in assert.cpp where `llvm_assert_trap` is
left unused depending on what's been defined and how the preprocessor
directives execute. This needs to be remedied so that the function is
only defined when it is used.
