Now that #149310 has restricted lifetime intrinsics to only work on allocas, we can also drop the explicit size argument. Instead, the size is implied by the alloca. This removes the ability to only mark a prefix of an alloca alive/dead. We never used that capability, so we should remove the need to handle that possibility everywhere (though many key places, including stack coloring, did not actually respect this).

; When consolidating PHINodes, the outliner replaces the incoming value with
|
|
; a corresponding value from the first outlined section. When this replaced
|
|
; value is passed in as an argument, the corresponding value is found outside
|
|
; of the outlined region, and must be replaced with an argument to avoid
|
|
; dominating value errors. This checks that we use the argument to replace
|
|
; the incoming value.
