Saleem Abdulrasool	c4e00289a7	ARM: correct WoA __builtin_alloca handling on O0 When performing a dynamic stack adjustment without optimisations, we would mark SP as def and R4 as kill. This occurred as part of the expansion of a WIN__CHKSTK SDNode which indicated the proper handling of SP and R4. The result would be that we would double define SP as part of an operation, which is obviously incorrect.

ARM: correct WoA __builtin_alloca handling on O0

When performing a dynamic stack adjustment without optimisations, we would mark
SP as def and R4 as kill.  This occurred as part of the expansion of a
WIN__CHKSTK SDNode which indicated the proper handling of SP and R4.  The result
would be that we would double define SP as part of an operation, which is
obviously incorrect.

Furthermore, the VTList for the chain had an incorrect parameter type of i32
instead of Other.

Correct these to permit proper lowering of __builtin_alloca at -O0.
