This fixes test/CodeGen/X86/2006-05-11-InstrSched.ll
Thanks to Evan Cheng for noticing this.

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.

Completely rewrite llvm-upgrade. This should be its final design. Any future
changes will use this same design. The changes involve the following:
1. Make this work very much like the 1.9 AsmParser
2. Retain old upgrades dating back to release 1.2 time frame.
3. Merge in some of the upgrades between 1.9 and 2.0 (e.g. icmp/fcmp).
4. Attach a Signedness value (Signless, Unsigned, Signed) to every type,
Value, Constant, Instruction, and list of those things in the Parser.
Use these to make signedness decisions for instruction upgrades.
5. Implement unique name upgrade for function values and global values.
6. Identify rename cases that might cause problems and warn about them.
For example: renaming a global variable with external linkage.
7. Generate a 2.0 IR using VMCore. This is necessary for numerous
reasons and has the advantage that it never goes out of date.
8. Use the AsmPrinter to make the output nice.
9. Clean up error and warning messages from 1.9 form.

The Module::setEndianness and Module::setPointerSize methods have been
removed. Instead you can get/set the DataLayout. Adjust thise accordingly.

Remove the Endianness and PointerSize fields from the ModuleHeader and
replace it with the DataLayout field.

BCReader no longer has a header that contains the endinanness and
pointer size. It's been replaced by datalayout field.

Remove the setEndianess and setPointerSize methods. These are now
handled via the setDataLayout method.

Remove the setEndiannes and setPointerSize methods. These are now set
through the setDataLayout method.

Implement separation of local and global symbols. Local symbols and types
now use % prefix. Global variables and functions now use @ prefix.
For PR761:
Replace:
target endian =
target pointersize =
With:
target datalayout =

Implement new syntax for local and global symbols. Types and local
symbols use the % prefix. Global variables and functions use the @ prefix.
