Beta match SpheresIntersect

[disinvite]

This is the second function degraded by the change to effective matching in isledecomp/reccmp#323. The diff is:

mov esi, dword ptr [eax + 4]
+fld dword ptr [esi + 4]
+mov edx, dword ptr [ecx + 4]
+fsub dword ptr [edx + 4]
fld dword ptr [esi + 8]
-mov edx, dword ptr [ecx + 4]
fsub dword ptr [edx + 8]
-fld dword ptr [esi + 4]
-fsub dword ptr [edx + 4]

This should be an effective match, but I thought I could force 100% by matching the beta. No luck there.

WriteDefaultTexture dropped a bit in this PR, but scored 89.45% for me with 256 entropy samples.

SpheresIntersect is a non-effective 100% match in the latest entropy build.

I also added a few other beta addresses I spotted while reviewing this.
