  [analyzer] Fix crashing __builtin_bit_cast (#139188)

Previously, CSA did not handle __builtin_bit_cast correctly. It
evaluated the LvalueToRvalue conversion for the casting expression,
but did not actually convert the value of the expression to be of the
destination type.
This commit fixes the problem.
