cb0fc1ce41 Do not hack on volatile loads. I'm not sure what the point of a volatile load 
from constant memory is, but lets not take chances.

4bfeceb15a New testcase, allow folding of binary operators that use PHI nodes, as long 
as the result of the binary operator is always constant.  This does not require
the PHI itself to be constant though.

68bae4ff19 This isn't really an assembler test. This tests to make sure the 
ConstantExpr::getGetElementPtr method folds two getelementptr instructions
when possible.

ef7c077e63 Make LiveVariables::HandlePhysRegUse and 
LiveVariables::HandlePhysRegDef private they use information that is
not in memory when LiveVariables finishes the analysis.

Also update the TwoAddressInstructionPass to not use this interface.

734c9747df Check in two changes: 
The first change (which is disabled) compactifies all of the function constant
pools into the global constant pool, in an attempt to reduce the amount of
duplication and overhead.  Unfortunately, as the comment indicates, this is
not yet a win, so it is disabled.

The second change sorts the typeid's so that those types that can be used
by instructions in the program appear earlier in the table than those that
cannot (such as structures and arrays).  This causes the instructions to
be able to use the dense encoding more often, saving about 5K on 254.gap.
This is only a .65% savings though, unfortunately. :(

06e5894c37 Update obsolete comments 
Fix iterator invalidation problems which was causing -mstrip to miss some
entries, and read free'd memory.  This shrinks the symbol table of 254.gap
from 333 to 284 bytes!  :)

accd21042c Do not bother to emit a BytecodeBlock for an empty symbol table. This commonly 
occurs when the symbol table for a module has been stripped, making all of the
function local symbols go away.

This saves 6728 bytes in the stripped bytecode file of 254.gap (which obviously
has 841 functions), which isn't a ton, but helps and was easy.

1eeb1b1c04 Finegrainify namespacification. 
This should get hunked over to the Sparc backend, along with
MachineCodeForInstruction and a bunch of files in include/llvm/Codegen,
but those battles will have to wait for a later time.
