[PATCH] Rename lld:*_error::_ -> lld:*_error::ErrorCode.

[Shankar Kalpathi Easwaran]

  <--snip--->
  Enumerators (e.g. enum { Foo, Bar }) and public member variables should start with an upper-case letter, just like types. Unless the enumerators are defined in their own small namespace or inside a class, enumerators should have a prefix corresponding to the enum declaration name. For example, enum ValueKind { ... }; may contain enumerators like VK_Argument, VK_BasicBlock, etc. Enumerators that are just convenience constants are exempt from the requirement for a prefix.

  This is not being considered.
