14eff5d627 - Add "Bitcast" target instruction property for instructions which perform 
nothing more than a bitcast.
- Teach tablegen to automatically infer "Bitcast" property.

5a51ccdc0f X86 table-generator and disassembler support for the AVX 
instruction set.  This code adds support for the VEX prefix
and for the YMM registers accessible on AVX-enabled
architectures.  Instruction table support that enables AVX
instructions for the disassembler is in an upcoming patch.

c7548fce48 Teach TableGen to pre-calculate register enum values when creating the 
CodeGenRegister entries. Use this information to more intelligently build
the literal register entires in the DAGISel matcher table. Specifically,
use a single-byte OPC_EmitRegister entry for registers with a value of
less than 256 and OPC_EmitRegister2 entry for registers with a larger value.

d415589edc Revert r127073: "Introduce $(ECHOPATH) to print DOSish path string on MSYS bash for alternative of $(ECHO)." 
It broke the llvm-gcc-native-mingw32 buildbot, and we need all of them to be green for the 2.9 branch.

Takumi, please reapply after we branch, preferably with a fix ;-)

125709b0ea Fix the case where the number of jobs is less than the 
number of threads.  In that case make the number of threads
equal to the number of jobs and launch one jobs on each
thread.  This makes things work like make -j.

91cce6cc1d A new TableGen feature! (Not turned on just yet.) 
InstAlias<{alias}, {aliasee}>;

The InstAlias instruction should be able to go from the MCInst to the
{alias}. All of the information is there to match the MCInst with the
{aliasee}. From there, it's a simple matter to emit the {alias}, with the
correct operands from the {aliasee}.

The code this patch generates can be used by the InstPrinter to automatically
print out the alias without having to write special C++ code to handle the
situation.

This is a WIP, and therefore are several limitations. For instance, it cannot
handle AsmOperands at the moment. It also doesn't know what to do when two
{alias}es match the same {aliasee}. (Currently, it just ignores those two cases
and allows the printInstruction method to handle them.)

ce1bb42907 Add some options for building LLVM in different environments: 
--force-configure to force running configure before building.

--extra-llvm-config-flags
--extra-llvm-gcc-config-flags
--extra-gcc-config-flags

Pass additional argument to the various configure invocations.

This also eliminates a default build flavor because explicitly
specifying builds could result in build flavors being run repeatedly.

Finally, turn off fortran builds for the moment because install
appears to be broken.
