Akira Hatanaka d918f77ba3 Insert instructions to the entry basic block which initializes the global
pointer register. 


This is the first of the series of patches which clean up the way global pointer
register is used. The patches will make the following improvements:

- Make $gp an allocatable temporary register rather than reserving it.
- Use a virtual register as the global pointer register and let the register
  allocator decide which register to assign to it or whether spill/reloads are
  needed.
- Make sure $gp is valid at the entry of a called function, which is necessary
  for functions using lazy binding.
- Remove the need for emitting .cprestore and .cpload directives.

Akira Hatanaka 4c0db08880 This patch fixes 3 problems:
1. CHECKNEXT was used instead of CHECK-NEXT which caused the line to be
   ignored which in turn hid the next 2 problems:
2. ('sh_offset', 0x{{{[0-9,a-f]+}}) had one too many leading curly braces and
   failed to do it's job of accepting all hex digits and:
3. The check for the hex values for the code instructions didn't account for
   blank separators.

Akira Hatanaka 3e9d81f47c Do not add offset in applyFixup. This has already been accounted for in Value.

Akira Hatanaka b1f68f9696 Initial 64 bit direct object support.
This patch allows llvm to recognize that a 64 bit object file is being produced
and that the subsequently generated ELF header has the correct information.

The test case checks for both big and little endian flavors.

Eli Bendersky f33086052d Continue cleanup of LIT, getting rid of the remaining artifacts from dejagnu
* Removed test/lib/llvm.exp - it is no longer needed 
* Deleted the dg.exp reading code from test/lit.cfg. There are no dg.exp files
  left in the test suite so this code is no longer required. test/lit.cfg is
  now much shorter and clearer 
* Removed a lot of duplicate code in lit.local.cfg files that need access to
  the root configuration, by adding a "root" attribute to the TestingConfig
  object. This attribute is dynamically computed to provide the same
  information as was previously provided by the custom getRoot functions. 
* Documented the config.root attribute in docs/CommandGuide/lit.pod

Akira Hatanaka 0137dfe42a Incremental big endian patch by Jack Carter.
These changes allow us to compile big endian from the command line for 32 bit
Mips targets. This patch will result in code and data actually being produced
in the correct endianess.

Eli Bendersky 924f9a671d Replace all instances of dg.exp file with lit.local.cfg, since all tests are run with LIT now and now Dejagnu. dg.exp is no longer needed.
Patch reviewed by Daniel Dunbar. It will be followed by additional cleanup patches.
