044439c9bc eliminate MCAsmInfo::NeedsSet: we now just use .set on any platform
that has it.

3622f9d328 Tweak the way appendModuleInlineAsm works, so you aren't obliged
to append a newline when using setModuleInlineAsm in case later
someone calls appendModuleInlineAsm - make newline handling fully
automatic.  In case anyone is wondering there is only one user of
appendModuleInlineAsm: the dragonegg plugin.

50c248824a Remove unneeded checks from configure.ac.
HAVE_{BI,STD,FWD}_ITERATOR and HAVE_NAMESPACES were not used in the code.
bison and flex are no longer used.
CAN_DLOPEN_SELF was never used either.
AC_PROG_LIBTOOL is not needed since we don't use libtool, we only need the
libltdl checks for dlopen.
Add check for AR, it used to be done by AC_PROG_LIBTOOL.
AC_TYPE_SIGNAL is deprecated, follow autoupdate's suggestion and replace with
void.
Remove unused m4 files.
Configure can now be generated using autoconf 2.65 too, without any warnings!

d87c50833a Move getJTISymbol from MachineJumpTableInfo to MachineFunction,
which is more convenient, and change getPICJumpTableRelocBaseExpr
to take a MachineFunction to match.

Next, move the X86 code that create a PICBase symbol to
X86TargetLowering::getPICBaseSymbol from 
X86MCInstLower::GetPICBaseSymbol, which was an asmprinter specific 
library.  This eliminates a 'gross hack', and allows us to
implement X86ISelLowering::getPICJumpTableRelocBaseExpr which now
calls it.

This in turn allows us to eliminate the 
X86AsmPrinter::printPICJumpTableSetLabel method, which was the
only overload of printPICJumpTableSetLabel.

b020478ce5 simplify asmprinter: only emit .set directives when entries have
EK_LabelDifference32 kind and the target has .set support.  Simplify
X86AsmPrinter::printPICJumpTableSetLabel to make use of recent helpers.

945bbf606f rename printPICJumpTableEntry -> EmitJumpTableEntry,
make it private and non-virtual.  It handles the non-pic
case too, so just use it, simplifying EmitJumpTableInfo.

7d88592ba1 implement X86 @GOTOFF jump table entries with the new EK_Custom32
jump table entry kind, instead of overloading 
AsmPrinter::printPICJumpTableEntry.

This has a pretty horrible and inefficient FIXME around how @GOTOFF
is currently smashed into the mcsymbol name, but otherwise this is
much cleaner.

91856859d6 New PBQP solver.
* Fixed a reduction bug which occasionally led to infinite-cost (invalid)
  register allocation solutions despite the existence finite-cost solutions.
* Significantly reduced memory usage (>50% reduction).
* Simplified a lot of the solver code.

5e06a05a16 Fix the the ceiling-division used in computing the MaxBECount so that it doesn't
have trouble with an intermediate add overflowing. Also, be more conservative
about the case where the induction variable in an SLT loop exit can step past
the RHS of the SLT and overflow in a single step.

Make getSignedRange more aggressive, to recover for some common cases which
the above fixes pessimized.

This addresses rdar://7561161.

416de57b74 don't bother setting the AsmPrinter::MF ivar, now that
AsmPrinter::SetupMachineFunction sets it.  Note that systemz
and msp430 didn't.  Yay for reduced inconsistency! :)

d25ec1b3bd make MachineFunction keep track of its ID and make
MachineFunctionAnalysis dole them out, instead of having
AsmPrinter do both.  Have the AsmPrinter::SetupMachineFunction
method set the 'AsmPrinter::MF' variable.
