bd02c60d9e make PIC16 unique its own sections instead of having mcontext do it.

7ead5b498b add some comments: MCContext owns the MCSections, but it bump pointer allocates 
them, so it doesn't have to explicitly free them.

9c9c3f30bd Now that numbered types have their number printed, it's no longer 
interesting to print the number in a comment. Numbered instructions
don't need their number in a comment either.

Also, tidy up newline printing.

and unnamed numbered global variables as "@0 = global ...". Extend the
AsmParser to recognize these forms.

d5c0351c79 Add a new "SDTCisVec" SDTypeConstraint. This complements the vAny type. 
There have been a few times where I've wanted this but ended up leaving the
operand type unconstrained.  It is easy to add this now and should help
catch errors in the future.

9b4700f3ce Make AsmWriter more careful with formatted_raw_ostream so that 
it doesn't leave the underlying stream in unbuffered mode when
the stream was originally buffered.

Also, change WriteAsOperand back to plain raw_ostream. This
lets it work for either formatted_raw_ostream or plain
raw_ostream, so that it doesn't have to force a buffer flush
on a plain raw_ostream.

9f80d2be6b Make LLVM Assembly dramatically easier to read by aligning the comments, 
using formatted_raw_ostream's PadToColumn.

Before:

bb1:            ; preds = %bb
  %2 = sext i32 %i.01 to i64            ; <i64> [#uses=1]
  %3 = getelementptr double* %p, i64 %2         ; <double*> [#uses=1]
  %4 = load double* %3, align 8         ; <double> [#uses=1]
  %5 = fmul double %4, 1.100000e+00             ; <double> [#uses=1]
  %6 = sext i32 %i.01 to i64            ; <i64> [#uses=1]
  %7 = getelementptr double* %p, i64 %6         ; <double*> [#uses=1]

After:

bb1:                                        ; preds = %bb
  %2 = sext i32 %i.01 to i64                ; <i64> [#uses=1]
  %3 = getelementptr double* %p, i64 %2     ; <double*> [#uses=1]
  %4 = load double* %3, align 8             ; <double> [#uses=1]
  %5 = fmul double %4, 1.100000e+00         ; <double> [#uses=1]
  %6 = sext i32 %i.01 to i64                ; <i64> [#uses=1]
  %7 = getelementptr double* %p, i64 %6     ; <double*> [#uses=1]

Several tests required whitespace adjustments.

61f35e39cf Fix TableGen warnings. This partly reverts my previous change to this file, 
leaving the mayLoad and mayStore settings around only the load/store
instructions where those can't be inferred from the patterns.
