Change some <>'s into &lt;&gt;'s

This substantially shrinks the size of each machine instruction, which should
make allocation faster and the cache footprint of the machine code lighter.

Here are some timings for code generation of the larger benchmarks we have.
This are timings of code generation phases of the X86 JIT, when compiled in
debug mode:

  InstSel	0.0878	0.0722	-21.6%

The shell AND/OR operators short-circuit on command success/failure, which is
the inverse of exit status (i.e. 0 means success, non-zero means failure).

	o Not all versions of diff have the -q option
	o The cmp program is probably faster than diff
Fixed the logic that only copies the file over if no differences are found.

1) Check that trapping instructionns that are not guaranteed to execute are not hoisted.
2) Check that trapping instructions that are guaranteed to execute are hoisted.

  * Expand most tabs into spaces
  * Move #define DEBUG_TYPE to top of file to avoid warning

Added function mergeInGlobalsGraph which merges in the entire globals graph with the graph of a function

Major bug fixes including a memory leak and tracking some exceptional conditions. Also added support for including global and indirect call information in the DS graphs used by the pool allocation

so get rid of the def/use parameters that were getting passed in.

**** This now changes the semantics of these methods to preserve the flags,
     not clobber them!

since those bits are now hard-coded in Sparc*.td files.

  Instruction.

operands if they are uninitialized AND used in the "Inst" field.

Physical registers should not float around.
