4aa2739696 This: 
AggregateString += "\0\0";

Doesn't add two nuls to the AggregateString (for obvious reasons), which
broke the asmprinter when the first character of an asm string was not
literal text.

10e06fa138 Add support for ${:foo} syntax, where "foo" is passed into "printSpecial" and 
has no associated operand.  This is useful for portably encoding stuff like
the comment character into an asm string.

f82eb13e3b 1) With X86 lowering change, the following can no longer happen since 
the branch's chain is also produced by cmp.
          [ch, r : ld]
             ^ ^
             | |
      [XX]--/   \- [flag : cmp]
       ^             ^
       |             |
       \---[br flag]-

Remove an isel check which prevents loads from being folded into cmp / test
instructions.

2) Whenever possible, delete a selected node to allow more load folding
opportunities. Note not all nodes can be deleted after it has been
selected. Some may have simply morphed; some have not changed at all (e.g.
EntryToken).

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.

e309e97cbd Count the documentation. Otherwise we take a 30,000 hit in the LOC on the

283f511a60 Use the new -code-only option to llvmdo so that we only count things that 
are considered to be code. This will give a drop in the LOC count on the
nightly testers, but it is more accurate than previous estimates.
