* Remove blank line

* BitPat supports whitespace and underscores, presumably for human readability.

Data.isLit called Data.litArg which would trigger a Chisel runtime
deprecation warning in user code with source locator Data.scala:488

(cherry picked from commit afef8b8c)

This switches from using an implicit val that required awkward
suppression (as illustrated in CompileOptionsSpec) to allowing
overriding in the same way as done in "import chisel3._" via the
creation of an implicit val in lexical scope.

(cherry picked from commit 77d2455a)

Accomplished by changing the code gen for casting literals to
aggregates. Rather than connecting the literal to a wire that is then
bit selected from, just bit select from the literal which saves the
creation of an intermediate wire and matches FIRRTL's semantics for
legal async reset initial values.
