Duncan P. N. Exon Smith 852e00e3d1 verify-uselistorder: Change the default -num-shuffles=5
Change the default for `-num-shuffles` to 5 and better document the
algorithm in the header docs of `verify-uselistorder`.

Duncan P. N. Exon Smith 5faa6225ad verify-uselistorder: Add RUN lines to cases in test/Assembly
Add RUN line for `verify-uselistorder` to every test in `test/Assembly`,
unless it's a negative check (assembler rejects it) or verification
fails.

There are three files that verification fails on (so I've left out the
RUN lines):

  - 2002-08-22-DominanceProblem.ll
  - ConstantExprFold.ll
  - ConstantExprFoldCast.ll

This is part of PR5680.

Chris Lattner b1ed91f397 Land the long talked about "type system rewrite" patch. This
patch brings numerous advantages to LLVM.  One way to look at it
is through diffstat:
 109 files changed, 3005 insertions(+), 5906 deletions(-)

Removing almost 3K lines of code is a good thing.  Other advantages
include:

1. Value::getType() is a simple load that can be CSE'd, not a mutating
   union-find operation.
2. Types a uniqued and never move once created, defining away PATypeHolder.
3. Structs can be "named" now, and their name is part of the identity that
   uniques them.  This means that the compiler doesn't merge them structurally
   which makes the IR much less confusing.
4. Now that there is no way to get a cycle in a type graph without a named
   struct type, "upreferences" go away.
5. Type refinement is completely gone, which should make LTO much MUCH faster
   in some common cases with C++ code.
6. Types are now generally immutable, so we can use "Type *" instead 
   "const Type *" everywhere.

Downsides of this patch are that it removes some functions from the C API,
so people using those will have to upgrade to (not yet added) new API.  
"LLVM 3.0" is the right time to do this.

There are still some cleanups pending after this, this patch is large enough
as-is.

Gabor Greif d01c562e48 Eliminate questionable syntax for stdin redirection. This probably also speeds things up a bit.

Reid Spencer e7df634b3d Fix the syntax for these tests. Noticed by Duncan Sands.

Reid Spencer ce380568b5 For PR761:
Remove "target endian/pointersize" or add "target datalayout" to make
the test parse properly or set the datalayout because defaults changes.

For PR645:
Make global names use the @ prefix.

For llvm-upgrade changes:
Fix test cases or completely remove use of llvm-upgrade for test cases
that cannot survive the new renaming or upgrade capabilities.
