Richard Barton b59aee170f [ARM] Fix offset calculation in ARMBaseRegisterInfo::needsFrameBaseReg 
The input offset to needsFrameBaseReg is a negative value below the top of the
stack frame, but when converting to a positive offset from the bottom of the
stack frame this value was negated, causing the final offset to be too large
by twice the input offset's magnitude. Fix that by not negating the offset.

; This test is fairly fragile. The goal is to ensure that "large" stack
; objects are allocated closest to the stack protector (i.e., farthest away
; from the Stack Pointer.) In standard SSP mode this means that large (>=
; ssp-buffer-size) arrays and structures containing such arrays are
; closet to the protector. With sspstrong and sspreq this means large
; arrays/structures-with-arrays are closest, followed by small (< ssp-buffer-size)
; arrays/structures-with-arrays, and then addr-taken variables.
;
; Ideally, we only want verify that the objects appear in the correct groups
; and that the groups have the correct relative stack offset. The ordering
; within a group is not relevant to this test. Unfortunately, there is not
; an elegant way to do this, so just match the offset for each object.
