This patch adds TruncOp for Math, it returns the operand rounded to the nearest integer not larger in magnitude than the operand. And this patch also adds the correspond llvm intrinsic op.

This is similar to math.round, but rounds to even instead of rounding away from
zero in the case of halfway values. This CL also adds lowerings to libm and
to the LLVM intrinsic.

The LLVM intrinsic has a bool flag `is_int_min_poison` that needs to be
set.

Adds an integer absolute value op to the math dialect.
When converting to LLVM, this op is lowered to the LLVM `abs` intrinsic.
When converting to SPIRV, this op is lowered to `spv.GL.SAbs`.
Depends on D131325

Introduce RoundOp in the math dialect. The operation rounds the operand to the
nearest integer value in floating-point format. RoundOp lowers to LLVM
intrinsics 'llvm.intr.round' or as a function call to libm (round or roundf).

This commit moves FuncOp out of the builtin dialect, and into the Func
dialect. This move has been planned in some capacity from the moment
we made FuncOp an operation (years ago). This commit handles the
functional aspects of the move, but various aspects are left untouched
to ease migration: func::FuncOp is re-exported into mlir to reduce
the actual API churn, the assembly format still accepts the unqualified
`func`. These temporary measures will remain for a little while to
simplify migration before being removed.

These passes generally don't rely on any special aspects of FuncOp, and moving allows
for these passes to be used in many more situations. The passes that obviously weren't
relying on invariants guaranteed by a "function" were updated to be generic pass, the
rest were updated to be FunctionOpinterface InterfacePasses.
The test updates are NFC switching from implicit nesting (-pass -pass2) form to
the -pass-pipeline form (generic passes do not implicitly nest as op-specific passes do).

The last remaining operations in the standard dialect all revolve around
FuncOp/function related constructs. This patch simply handles the initial
renaming (which by itself is already huge), but there are a large number
of cleanups unlocked/necessary afterwards:
* Removing a bunch of unnecessary dependencies on Func
* Cleaning up the From/ToStandard conversion passes
* Preparing for the move of FuncOp to the Func dialect

Count leading/trailing zeros are an existing LLVM intrinsic. Added LLVM
support for the intrinsics with lowerings from the math dialect to LLVM
dialect.

After the Math has been split out of the Standard dialect, the
conversion to the LLVM dialect remained as a huge monolithic pass.
This is undesirable for the same complexity management reasons as having
a huge Standard dialect itself, and is even more confusing given the
existence of a separate dialect. Extract the conversion of the Math
dialect operations to LLVM into a separate library and a separate
conversion pass.

This provides a sizable compile time improvement by seeding
the worklist in an order that leads to less iterations of the
worklist.
This patch only changes the behavior of the Canonicalize pass
itself, it does not affect other passes that use the
GreedyPatternRewrite driver

Some Math operations do not have an equivalent in LLVM. In these cases,
allow a low priority fallback of calling the libm functions. This is to
give functionality and is not a performant option.
