Subject: ValueTypes.td: Introduce VTAny as `isOverloaded = true`
X-Git-Tag: upstream/17.0.6~10549
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3c853c845ad6ff1591f60a909fa3c7d293c27b49;p=platform%2Fupstream%2Fllvm.git

ValueTypes.td: Introduce VTAny as `isOverloaded = true`

`ValueType.isOverloaded` is used for;

  - Define `iPTRAny`, `vAny`, `fAny`, and `Any`
  - Reflect `ValueType.isOverloaded` to `LLVMType.isAny` in `Intrinsics.td`
  - (Planninig) Reflect the condition to `MVT::isOverloaded()`
