Test the upgradability of nested type definitions.

llvm-svn: 33534

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   reasons and has the advantage that it never goes out of date.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.

llvm-svn: 33530

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

llvm-svn: 33529

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 It's been replaced by datalayout field.

llvm-svn: 33528

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

llvm-svn: 33527

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

llvm-svn: 33526

llvm-svn: 33525

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 =

llvm-svn: 33524

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

llvm-svn: 33523

Remove the Function::renameLocalSymbols function as it is no longer
needed.

is unnecessary when we are fixing up a conditional branch since we will be
adding a unconditional branch to the destination of the original branch.

CallGraphSCCPass does not need to implement runOnModule().
It supports runOnSCC().

  It will have to be handled with dynamic aligning code.
