Subject: Add a few utility overloads for OpAsmParser methods:
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=08d407f243cbf9ee6292addc931b31bc52c4dcee;p=platform%2Fupstream%2Fllvm.git

Add a few utility overloads for OpAsmParser methods:
* Add a getCurrentLocation that returns the location directly.
* Add parseOperandList/parseTrailingOperandList overloads without the required operand count.
