Resubmit an earlier patch of mine:
reduce the size of relevant "ghostly" sentinels
by a pointer.

This attempt now makes the compactification dependent
on the configure variable LLVM_COMPACT_SENTINELS
and should not cause any bootstrap failures for
llvm-gcc any more.

Please note that this is not yet the final version,
and (as settled with Chris) I shall take out the
autofoo/cmake portions in the next days.

This will also lose the assertability on sentinel
dereferencing and operator++, but that seems
an acceptable price to pay for the simplified
build logic.

just remove interpreter support for endianness mismatches.  This was
really old code from when we were running sparcv9 bc files on x86
(before I ported llvm-gcc 3 to work on x86) :)

remove use of alloca.h

Prune #includes from llvm/Linker.h and llvm/System/Path.h,
forcing them down into various .cpp files.

This change also:
1. Renames TimeValue::toString() and Path::toString() to ::str()
   for similarity with the STL.
2. Removes all stream insertion support for sys::Path, forcing
   clients to call .str().
3. Removes a use of Config/alloca.h from bugpoint, using smallvector
   instead.
4. Weans llvm-db off <iostream>

sys::Path really needs to be gutted, but I don't have the desire to
do it at this point.

disuade people from using ostream.

Switch SubtargetFeature off of ostreams

eliminate the ostream version of CheckBitcodeOutputToConsole,
change the raw_ostream one to take the raw_ostream byref instead
of byptr.  Prune #includes, eliminate a use of Streams.h

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79863 91177308-0d34-0410-b5e6-96231b3b80d8

Fix off-by-one in llvm::Format::print.
 - This also shortens the Format.h implementation, and uses the print buffer
   fully (it was wasting a character).

 - This manifested as llvm-test failures, because one side effect was that
   raw_ostream would write garbage '\x00' values into the output stream if it
   happened that the string was at the end of the buffer. This meant that grep
   would report 'Binary file matches', which meant the silly pattern matching
   llvm-test eventually does would fail. Cute. :)

Rerevert (r75663 and r76805), seems there is more non-determinism.

Fix PR4753.

When undoing a reuse in ReuseInfo::GetRegForReload, check if it was only a
sub-register being used. The MachineOperand::getSubReg() method is only valid
for virtual registers, so we have to recover the sub-register index manually.

Fix non-determinism in DAGISel emitter.
 - This manifested as non-determinism in the .inc output in rare cases (when two
   distinct patterns ended up being equivalent, which is rather rare). That
   meant the pattern matching was non-deterministic, which could eventually mean
   the code generator selected different instructions based on the arch.

 - It's probably worth making the DAGISel ensure a total ordering (or force the
   user to), but the simple fix here is to totally order the Record* maps based
   on a unique ID.

 - PR4672, PR4711.

Yay:
