 By "implement this" I mean only if localloc asks for more than 8
 bytes, align to 8, otherwise do like we do now.

 It should always align to 8 bytes, it's pointless to add a check.

+There's one thing I don't understand in "always align to 8 bytes".
+Currently localloc aligns following MONO_ARCH_FRAME_ALIGNMENT, which
+is 4 only on ppc and on non-Windows x86.
+I really do not think I should give MONO_ARCH_FRAME_ALIGNMENT a new
+value, but that's OK, I could just define a new macro (like
+in almost all cases, and 8 in the others.
+Something like:
+maybe at the end of "mini-arch.h".
+But do you really mean that asking for 4 bytes (an int32) on x86
+and ppc should align it to 8 bytes, just to keep the code general
+and simple?
