just ask ScalarEvolution for it on demand. This helps IVUsers be more robust
in the case of expressions changing underneath it. This fixes PR6862.

Pseudocode details of conditional, Condition bits '111x' indicate the
instruction is always executed.  That is, '1111' is a leagl condition field
value, which is now mapped to ARMCC::AL.

Also add a test case for condition field '1111'.

a cmake guru could add a cmake check for posix_spawn as well.
