[mips] Parse the 'bopt' and 'nobopt' directives in IAS. The GAS assembler supports the ".set bopt" directive but according to the sources it doesn't do anything. It's supposed to optimize branches by filling the delay slot of a branch with it's target. This patch teaches the MIPS asm parser to accept both and warn in the case of 'bopt' that the bopt directive is unsupported. This resolves PR/31841. Thanks to Sean Bruno for reporting the issue! llvm-svn: 293798 2017-02-02 02:50:24 +08:00			`# RUN: llvm-mc -arch=mips -mcpu=mips32 %s 2>&1 \| FileCheck %s`
