The really painful part of this PR was updating all the test files. I had some help from Gemini GLI there which did a pretty good job (got maybe 80% of the updates done). Fixes: #151015

; Test that the --stack-first option places the stack at the start of linear
|
|
; memory. In this case the --stack-first option is being passed along with a
|
|
; stack size of 512. This means (since the stack grows down) the stack pointer
|
|
; global should be initialized to 512.
|
|
; Also test that __heap_base is still aligned with the --stack-first option.
