[tkreuzer] 45088: [CRT] Patch by Jose Catena: allmul produced wrong results when the higher 32 bits of any of the 64 bit operands are not zero. As the comment correctly said the definition of param locations must change since esp was altered, but the definitions were not actually changed See issue #5121 for more details.

Patch by Jose Catena:
allmul produced wrong results when the higher 32 bits of any of the 64 bit operands are
not zero. As the comment correctly said the definition of param locations must change
since esp was altered, but the definitions were not actually changed
