[AArch64] Remove unused MC function

An unused function warning was raised in
https://bugs.llvm.org/show_bug.cgi?id=34178.

The offending function, in AArch64MCCodeEmitter.cpp, was committed by
me last week.

Differential Revision: https://reviews.llvm.org/D36665

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@310823 91177308-0d34-0410-b5e6-96231b3b80d8
