talk to the MCStreamer directly instead.

a8f0bc04d3 Fix gcc-4.4/fedora 11 by adding a sentinel value to SimpleValueType.
gcc-4.4 was optimizing away comparisons against SimpleValueType when
it was compared to a value larger than the largest value in the enum.
This patch works around it by adding one extra item to the enum so
that these tests will now be valid.

ba43a385a8 Privatize part of the leak detector mechanism, which turned out to be heavily contended
when trying to run opt in parallel.  This lets parallel opt crunch 403.gcc in about a third

ab81027544 raw_ostream: Reduce FormattedStream's reliance on raw_ostream's implementation.
- Kill off begin(), end(), and iterator. It isn't clear what these
   mean. Instead provide getBufferStart(), which can be used with
   GetNumBytesInBuffer to the same effect.

 - Update ComputeColumn to take arguments for the buffer to scan, this
   simplifies the implementation of write_impl substantially.

 - This should also fix possible problems with the scanning pointer pointing
   outside of the current raw_ostream buffer.

c0823fe7c6 Simplify RegScavenger::FindUnusedReg.
- Drop the Candidates argument and fix all callers. Now that RegScavenger
  tracks available registers accurately, there is no need to restict the
  search.
- Make sure that no aliases of the found register are in use. This was a potential bug.

declined buffering.

da65822cfc Make tail merging handle blocks with repeated predecessors correctly, and
remove RemoveDuplicateSuccessor, as it is no longer necessary, and because
it breaks assumptions made in
MachineBasicBlock::isOnlyReachableByFallthrough.

Convert test/CodeGen/X86/omit-label.ll to FileCheck and add a testcase
for PR4732.

test/CodeGen/Thumb2/thumb2-ifcvt2.ll sees a diff with this commit due to
it being bugpoint-reduced to the point where it doesn't matter what the
condition for the branch is.

Add some more interesting code to
test/CodeGen/X86/2009-08-06-branchfolder-crash.ll, which is the testcase
that originally motivated the RemoveDuplicateSuccessor code, to help
verify that the original problem isn't being re-broken.

dabf07c70a Make AsmStreamer maintain a notion of the current section, pushing it up from the

and add an assert.  This change is in preparation for completely eliminating 
asmprinter::switchtosection.
