patch is a middle ground between the previously working and currently broken
situations: if the back-end defines STACK_DYNAMIC_OFFSET, then the middle-end
assumes that STACK_DYNAMIC_OFFSET maintains the alignment; if it doesn't,
which means the default value of STACK_DYNAMIC_OFFSET computed in function.c
is used instead, then the middle-end maintains the alignment itself.

I'd say let's not have a middle ground - this stuff is sufficientlybrain-twisting that I'd rather go back to a known working state. Ifthere was an error in the previous patch, let's roll it back until wefully understand the situation.
