c802d57e52 Input files should go before all other options. 
Important, for example, when calling 'gcc a.o b.o c.o -lD -lE -lF'.

8ea3f4a592 Add instruction flags: hasExtraSrcRegAllocReq and hasExtraDefRegAllocReq. When 
set, these flags indicate the instructions source / def operands have special
register allocation requirement that are not captured in their register classes.
Post-allocation passes (e.g. post-alloc scheduler) should not change their
allocations. e.g. ARM::LDRD require the two definitions to be allocated
even / odd register pair.

31fcbdefbb Introduce the TargetInstrInfo::KILL machine instruction and get rid of the 
unused DECLARE instruction.

KILL is not yet used anywhere, it will replace TargetInstrInfo::IMPLICIT_DEF
in the places where IMPLICIT_DEF is just used to alter liveness of physical
registers.

80d69b5973 implement and document support for filecheck variables. This 
allows matching and remembering a string and then matching and
verifying that the string occurs later in the file.

Change X86/xor.ll to use this in some cases where the test was
checking for an arbitrary register allocation decision.

b47463f436 remove support for "NoSub" from regex. It seems like a minor optimization 
and makes the API more annoying.  Add a Regex::getNumMatches() method.

0ac693a89e Improve MachineMemOperand handling. 
- Allocate MachineMemOperands and MachineMemOperand lists in MachineFunctions.
   This eliminates MachineInstr's std::list member and allows the data to be
   created by isel and live for the remainder of codegen, avoiding a lot of
   copying and unnecessary translation. This also shrinks MemSDNode.
 - Delete MemOperandSDNode. Introduce MachineSDNode which has dedicated
   fields for MachineMemOperands.
 - Change MemSDNode to have a MachineMemOperand member instead of its own
   fields with the same information. This introduces some redundancy, but
   it's more consistent with what MachineInstr will eventually want.
 - Ignore alignment when searching for redundant loads for CSE, but remember
   the greatest alignment.

Target-specific code which previously used MemOperandSDNodes with generic
SDNodes now use MemIntrinsicSDNodes, with opcodes in a designated range
so that the SelectionDAG framework knows that MachineMemOperand information
is available.

0c4e55a2f8 Rename getTargetNode to getMachineNode, for consistency with the 
naming scheme used in SelectionDAG, where there are multiple kinds
of "target" nodes, but "machine" nodes are nodes which represent
a MachineInstr.

2b1f7c6a75 reimplement the regex matching strategy by building a single 
regex and matching it instead of trying to match chunks at a time.
Matching chunks at a time broke with check lines like 
  CHECK: foo {{.*}}bar
because the .* would eat the entire rest of the line and bar would
never match.

Now we just escape the fixed strings for the user, so that something
like:
  CHECK: a() {{.*}}???
is matched as:
  CHECK: {{a\(\) .*\?\?\?}}
transparently "under the covers".

97cf81c3c6 Use CanonicalizeInputFile to canonicalize the entire buffer containing the 
CHECK strings, instead of canonicalizing the patterns directly.  This allows
Pattern to just contain a StringRef instead of std::string.

b8a623820a lit: When executing shell scripts internally, don't allow piped stderr on any 
commands except the last one, instead redirect the stderr to a temporary

06695b3ea1 Add a magic LLVM_DISABLE_CRT_DEBUG environment variable which we check in RegisterHandler and use to disable the Win32 crash dialogs. These are a major blocker to any kind of automated testing.
