[ValueTracking] fadd never produces subnormal with no underflow (#186985) 
In the cases where the fadd does not underflow, the result is both
non-zero and non-subnormal.

alive2 results for the added positive testcases:

testcase 1: https://alive2.llvm.org/ce/z/Mxjott

testcase 2: https://alive2.llvm.org/ce/z/Q-_A-v

testcase 3: https://alive2.llvm.org/ce/z/Y3XpSk

testcase 4: https://alive2.llvm.org/ce/z/34n8MZ

Fix #186975.
