[llvm] r268529 - [ARM] Fix Scavenger assert due to underestimated stack size

[Zhao, Weiming via llvm-commits]

I tried to build my local LLVM with Memory Sanitizer, but it failed 
because the generated llvmTblGen hit the same use-of-undef-var error.  
Do you know if there is any other way we can reproduce the error?

Thanks,

Weiming
