Now that it behaves itself in terms of streamer independence (r172450), this
method can be moved to MCAsmParser to be available to all extensions,
overriding, etc.

The aim of this patch is to fix the following piece of code in the
platform-independent AsmParser:

void AsmParser::CheckForValidSection() {
  if (!ParsingInlineAsm && !getStreamer().getCurrentSection()) {
    TokError("expected section directive before assembly directive");
    Out.SwitchSection(Ctx.getMachOSection(
                        "__TEXT", "__text",
                        MCSectionMachO::S_ATTR_PURE_INSTRUCTIONS,
                        0, SectionKind::getText()));
  }
}

This was added for the "-n" option of llvm-mc.

The proposed fix adds another virtual method to MCStreamer, called
InitToTextSection. Conceptually, it's similar to the existing
InitSections which initializes all common sections and switches to
text. The new method is implemented by each platform streamer in a way
that it sees fit. So AsmParser can now do this:

void AsmParser::CheckForValidSection() {
  if (!ParsingInlineAsm && !getStreamer().getCurrentSection()) {
    TokError("expected section directive before assembly directive");
    Out.InitToTextSection();
  }
}

Which is much more reasonable.

Since it's used by extensions. One further step to fully decoupling
GenericAsmParser from an intimate knowledge of the internals of AsmParser,
pointing it to the MCASmParser interface instead (like all other parser
extensions do).

Since this change moves the MacroArgument type to the interface header, it's
renamed to be a bit more descriptive in a general context.

llvm-svn: 172449

The methods are also exposed via the MCAsmParser interface, which allows more
than one client to control them. Previously, GenericAsmParser was playing with
a member var in AsmParser directly (by virtue of being its friend).
