Chris Lattner 0f68fa6569 Implement InstCombine/xor.ll:test(15|16)

Chris Lattner f622d7c31e New testcase for masking operation that frequently occurs in the pool allocator 
for converting a number that is a power of two into a mask

Alkis Evlogimenos 20d03bb166 Update documentation since it was misleading: make it clear that a 
negative instruction count is returned if instructions are removed
from a basic block.

Alkis Evlogimenos 9118a426d3 Change all machine basic block modifier functions in MRegisterInfo to 
return the number of instructions added to/removed from the basic block
passed as their first argument.

Note: This is only needed because we use a std::vector instead of an
ilist to keep MachineBasicBlock instructions. Inserting an instruction
to a MachineBasicBlock invalidates all iterators to the basic
block. The return value can be used to update an index to the machine
basic block instruction vector and circumvent the iterator elimination
problem but this is really not needed if we move to a better
representation.

Brian Gaeke 69c2841b2a Update verifySavedState()'s comment, so that it reflects its current 
status.  In doFinalization(), skip over external functions, just like
Anand's mapping info does.

Chris Lattner 604ac9cfc0 While working on the pool allocator, I noticed that basicaa is failing a scary 
number of simple cases.  Someday when I get a chance to work on it again, this
testcase should be corrected.

John Criswell 81587e798a Checking in Chris's suggestions: 
Added assert() to ensure symbol table is well formed.
Added code to remember the value that was found; resolving types can change
the symbol table and invalidate the value of the iterator.
Added comments to the ResolveTypes() function (mainly for my own benefit).
Please feel free to correct the comments if they are not accurate.

John Criswell 28f8fc669d Modified build rules so that a messages appears before and after linking. 
This helps to disambiguate when linking begins and when the library/program
is linked and ready to be used.
This is sort of as preference thing, so feel free to modify/revert the change.

Chris Lattner b71c3f7430 Significantly simplify constant emission by unifying the stuff which used to build up 
strings with the stuff that used to print to an ostream directly.  We now NEVER build
up big strings, only to print them once they are formed.

Chris Lattner 7be3ab2fb7 This simplifies the CWriter code, makes the generated code easier to read, 
and makes the output work with the intel compiler.  Overall, a win.

Chris Lattner 2b9926fc8e All DSGraphs keep a reference to the targetdata they are created with. This is 
used to eliminate the hard coded, hacked in, sparc specific, global TargetData.
Changing the TargetData used to actually match the code fixes problems, and
eliminates a crash.
