dbea6d7acb "This is just a cosmetic change in MCAsmStreamer.cpp/EmitSymbolAttribute: all attributes have now a \t before and after, as done for '.type'.
This makes the output look consistent, as well as help some third party assemblers expecting the attributes to be in the second column."

Patch by Arnaud de Grandmaison!

raw_ostream to print an instruction to had to be specified
at MCInstPrinter construction time instead of being able
to pick at each call to printInstruction.

4e8e791414 add a new EmitInlineAsm function to asmprinter to handle inline asm.
If we have an MCAsmStreamer, we continue to emit asm textually, 
otherwise we (currently) emit an error to errs and ignore it.

c11390f758 This is the first patch to put the needed bits in place to eventually allow code
to be aligned with optimal nops.  This patch does not change any functionality
and when the compiler is changed to use EmitCodeAlignment() it should also not
change the resulting output.  Once the compiler change is made and everything
looks good the next patch with the table of optimal X86 nops will be added to
WriteNopData() changing the output.  There are many FIXMEs in this patch which
will be removed when we have better target hooks (coming soon I hear).

df1b7b6164 Add the ability for MCStreamer to emit comments on the same line as directives.
Switch over the asm-verbose comment for double values to use it.  We now get:

	.long	1079953326

For example, note that the comment is on the same line as the .long.  Woo.
