[Anton Korobeynikov]

Changes in directory llvm/test/CodeGen/X86:

mingw-alloca.ll added (r1.1)
---
Log message:

Implemented correct stack probing on mingw/cygwin for dynamic alloca's. 
Also, fixed static case in presence of eax livin. This fixes PR331: http://llvm.org/PR331 

PS: Why don't we still have push/pop instructions? :)
