[mlir] Add better support for f80 and f128

[clementval]

Summary

Add builtin f80 and f128 following @schweitz proposition
https://llvm.discourse.group/t/rfc-adding-better-support-for-higher-precision-floating-point/2526/5

[rriddle]

Did a pass through, and looks good to me.

mlir/test/Dialect/LLVMIR/types.mlir

6–7

Can you add a usage in IR/parser.mlir now that these are builtin types? All of these checks here look like they should go away now that the types have been replaced.

[clementval]

Add usage in IR/parser.mlir

mlir/test/Dialect/LLVMIR/types.mlir

6–7

Should we also remove the checks for f16, bf16, f32, f64?

[rriddle]

mlir/test/Dialect/LLVMIR/types.mlir

6–7

Yeah, I don't think any of those are useful anymore.

[clementval]

Remove useless checks now that types have been replaced

[clementval]

mlir/test/Dialect/LLVMIR/types.mlir

6–7

Ok. Thanks for the quick review. I just removed the checks.

Please add f80 and f128 here

[clementval]

Add f80 and f128 to LLVM.md

mlir/docs/ConversionToLLVMDialect.md

 Scalar types are converted to their LLVM counterparts if they exist. The
 following conversions are currently implemented:
 
 -   `i*` converts to `!llvm.i*`
 -   `bf16` converts to `bf16`
 -   `f16` converts to `f16`
 -   `f32` converts to `f32`
 -   `f64` converts to `f64`
+-   `f80` converts to `f80`
+-   `f128` converts to `f128`
 
 ### Index Type
 
 Index type is converted to an LLVM dialect integer type with bitwidth equal to
 the bitwidth of the pointer size as specified by the
 [data layout](Dialects/LLVM.md#data-layout-and-triple) of the closest module.
 For example, on x86-64 CPUs it converts to `i64`. This behavior can be
 overridden by the type converter configuration, which is often exposed as a pass

mlir/docs/Dialects/LLVM.md

 pointer to a 32-bit integer.
 
 ### Built-in Type Compatibility
 
 LLVM dialect accepts a subset of built-in types that are referred to as _LLVM
 dialect-compatible types_. The following types are compatible:
 
 -   Signless integers - `iN` (`IntegerType`).
--   Floating point types - `bfloat`, `half`, `float`, `double` (`FloatType`).
+-   Floating point types - `bfloat`, `half`, `float`, `double` , `f80`, `f128`
+    (`FloatType`).
 -   1D vectors of signless integers or floating point types - `vector<NxT>`
     (`VectorType`).
 
 Note that only a subset of types that can be represented by a given class is
 compatible. For example, signed and unsigned integers are not compatible. LLVM
 provides a function, `bool LLVM::isCompatibleType(Type)`, that can be used as a
 compatibility check.
 
 ### Additional Simple Types
 
 The following non-parametric types derived from the LLVM IR are available in the
 LLVM dialect:
 
--   `!llvm.fp128` (`LLVMFP128Type`) - 128-bit floating-point value as per
-    IEEE-754-2008.
--   `!llvm.x86_fp80` (`LLVMX86FP80Type`) - 80-bit floating-point value (x87).
 -   `!llvm.x86_mmx` (`LLVMX86MMXType`) - value held in an MMX register on x86
     machine.
 -   `!llvm.ppc_fp128` (`LLVMPPCFP128Type`) - 128-bit floating-point value (two
     64 bits).
 -   `!llvm.token` (`LLVMTokenType`) - a non-inspectable value associated with an
     operation.
 -   `!llvm.metadata` (`LLVMMetadataType`) - LLVM IR metadata, to be used only if
     the metadata cannot be represented as structured MLIR attributes.

 #### Floating Point Types
 
 Syntax:
 
 ```
 // Floating point.
-float-type ::= `f16` | `bf16` | `f32` | `f64`
+float-type ::= `f16` | `bf16` | `f32` | `f64` | `f80` | `f128`
 ```
 
 MLIR supports float types of certain widths that are widely used as indicated
 above.
