Optimize the loading of an identifier from a PCH file when given the identifier's ID. In this case, we know where the identifier's entry is located in the hash table (it starts right before the identifier string itself), so skip the hash table lookup and read the entry directly. The performance improvement here is, gain, hard to quantify, but it's the right thing to do. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70078 91177308-0d34-0410-b5e6-96231b3b80d8
