59a4d8dfcd Fix a long-standing wart in the code generator: two-address instruction lowering 
actually *removes* one of the operands, instead of just assigning both operands
the same register.  This make reasoning about instructions unnecessarily complex,
because you need to know if you are before or after register allocation to match
up operand #'s with the target description file.

Changing this also gets rid of a bunch of hacky code in various places.

This patch also includes changes to fold loads into cmp/test instructions in
the X86 backend, along with a significant simplification to the X86 spill
folding code.

b96b719724 - Clean up tablegen dag isel generator code. 
- Clean up the code generated by tablegen:
  * AddToISelQueue now takes one argument.
  * ComplexPattern matching condition can now be shared.
  * Eliminate passing unnecessary arguments to emit routines.
  * Eliminate some unneeded SDOperand declarations in select routines.
  * Other minor clean ups.
- This reduces foot print slightly: X86ISelDAGToDAG.o is reduced from 971k
  to 823k.

6c18e5e7b7 Corrected an error that was introduced yesterday that caused the GCC 
version to be left blank if the build failed.

Also corrected a problem where if the build failed the nightly tester
would still try to read the results of the Dejagnutests log even
though it didnt exist.

7f2ce5b626 Make all tools that use llvmdo have a -topdir option that allows the top 
source dir for LLVM to be specified explicitly. This removes the dependency
on the llvm-config script. If the option is not given, then the scripts use
llvm-config which should be both built and in the PATH. This arrangement
provides a useful default for most developers but also allows the nightly
tester to execute countloc.sh before llvm-config is built and without
altering the PATH.

  4. Put { on same line as if statement.
  5. Make indentation be 2 spaces.

5950c56f73 - Prevent some functions from being inlined to eliminate the code size bloat 
introduced by previous commit.
- SelectCode now returns a SDNode*. If it is not null, the selected node
  produces the same number of results as the input node. The seletion loop
  is responsible for calling ReplaceAllUsesWith() to replace the input node
  with the output target node. For other cases, e.g. when load is folded,
  the selection code is responsible for calling ReplaceAllUsesOfValueWith()
  and SelectCode returns NULL.
- Other clean ups.

7b1362fa52 Start eliminating temporary vectors used to create DAG nodes. Instead, pass 
in the start of an array and a count of operands where applicable.  In many
cases, the number of operands is known, so this static array can be allocated
on the stack, avoiding the heap.  In many other cases, a SmallVector can be
used, which has the same benefit in the common cases.

I updated a lot of code calling getNode that takes a vector, but ran out of
time.  The rest of the code should be updated, and these methods should be
removed.

We should also do the same thing to eliminate the methods that take a
vector of MVT::ValueTypes.

It would be extra nice to convert the dagiselemitter to avoid creating vectors
for operands when calling getTargetNode.

09f9f995f5 Split each select function for a particular opcode into multiple ones. One 
per possible ValueType of the node. e.g. Select_add is split into Select_add_i8,
Select_add_i16, etc.

For opcodes which do not produce a non-chain result, it is split on the
ValueType of its first non-chain operand. e.g. Select_store.

On X86 / Mac OS X, Select_store used to be the largest function. It had a stack
frame size of 8.5k. Now the largest one is Store_i32 with a frame size of 3.1k.

dc6201bb05 Changes to support cross-compiling LLVM. The GenLibDeps.pl script needs to 
have a compile-host version of "nm", not build-host. In order to effect this
we must use autoconf to determine the correct "nm" to use and propagate that
through the makefiles, through llvm-config and finally to GenLibDeps.pl as
an optional argument.
