Lei Zhang ee062769e3 Fix the MSVC build. 
In LiftoffCompiler::EmitTypeConversion() there is a DCHECK_EQ() where
one argument is implicitly converted to bool. This confuses MSVC, which
causes it to think the two arguments to DCHECK_EQ() do not have the same
type. Fix this with an explicit bool conversion!!

This does not affect the "v8_win64_msvc_compile_rel" bot, presumably
because it is a release bot with DCHECKs turned off.
