These are identified by misc-include-cleaner. I've filtered out those
that break builds. Also, I'm staying away from llvm-config.h,
config.h, and Compiler.h, which likely cause platform- or
compiler-specific build failures.
This commit adds the initial version of the mlir-query tool, which leverages the pre-existing matchers defined in mlir/include/mlir/IR/Matchers.h
The tool provides the following set of basic queries:
hasOpAttrName(string)
hasOpName(string)
isConstantOp()
isNegInfFloat()
isNegZeroFloat()
isNonZero()
isOne()
isOneFloat()
isPosInfFloat()
isPosZeroFloat()
isZero()
isZeroFloat()
