ARM cost model: Fix costs for some vector selects
I was too pessimistic in r177105. Vector selects that fit into a legal register

an address.
Changing the code fragment to:
%T0_3 = type <8 x i18>
%T1_3 = type <8 x i1>
define void @func_blend3(%T0_3* %loadaddr, %T0_3* %loadaddr2,

Perform factorization as a last resort of unsafe fadd/fsub simplification.
Rules include:
1)1 x*y +/- x*z => x*(y +/- z)
(the order of operands dosen't matter)
2) y/x +/- z/x => (y +/- z)/x
The transformation is disabled if the new add/sub expr "y +/- z" is a
denormal/naz/inifinity.

Implements memoization for ancestor matching.
This yields a log(#ast_nodes) worst-case improvement with matchers like
stmt(unless(hasAncestor(...))).
Also made the order of visitation for ancestor matches BFS, as the most
common use cases (for example finding the closest enclosing function
definition) rely on that.
