This is the final patch for this PR. It implements some minor cleanup

Clean up some code around the store V, (cast P) -> store (cast V), P
...
transform. Change some variable names so it is clear what is source and
what is dest of the cast. Also, add an assert to ensure that the integer
to integer case is asserting if the bitwidths are different. This prevents
illegal casts from being formed and catches bitwidth bugs sooner.

Fix PR1114 and CodeGen/Generic/2007-01-15-LoadSelectCycle.ll by being

careful when folding "c ? load p : load q" that C doesn't reach either load.
If so, folding this into load (c ? p : q) will induce a cycle in the graph.

Fix for PR1095:

LLVM would miscompile ASM dialects when compiling for PPC. Added dialects for
the X86 and PPC backends. It defaults to "0", the first variant of a compound

Don't print address of ETNode. Print the DFSNumIn which uniquely identifies

the basic block and is stable across runs in gdb or valgrind.
Make Node::update handle edges which dominate and are tighter than
existing edges.
Replace makeEqual's "squeeze theorem" code. Fixes miscompilation.
Gate the calls to defToOps and opsToDef. Before this, we were getting IG
edges about values which weren't even defined in the dominated area. This
reduces the size of the IG by about half.

For PR1064:
...
Implement the arbitrary bit-width integer feature. The feature allows
integers of any bitwidth (up to 64) to be defined instead of just 1, 8,
16, 32, and 64 bit integers.
This change does several things:
1. Introduces a new Derived Type, IntegerType, to represent the number of
bits in an integer. The Type classes SubclassData field is used to
store the number of bits. This allows 2^23 bits in an integer type.
2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and
64-bit integers. These are replaced with just IntegerType which is not
a primitive any more.
3. Adjust the rest of LLVM to account for this change.
Note that while this incremental change lays the foundation for arbitrary
bit-width integers, LLVM has not yet been converted to actually deal with
them in any significant way. Most optimization passes, for example, will
still only deal with the byte-width integer types. Future increments
will rectify this situation.

For PR1099:
...
Invert the "isSigned" logic in calls to printType and printPrimitiveType.
We want variables to be declared unsigned by default so that signless
operators like + and - perform the unsigned operation that LLVM expects
by default. Parameters with the sext attribute will be declared signed and
signed instructions will case operand values to signed regardless of the
type of the variable. This passes all tests and fixes PR1099.

For PR1099:
...
Partial fix for this PR. Default function parameters to signed integer, just
like everything else in CBE. The bug was caused by incorrectly introducing
parameter attributes feature by choosing "signed" parameter if the
SExtAttribute was specified. Howeer, if no attribute is specified, this
causes it to become unsigned which is incorrect. Reversing the logic so
that signedness is detected by "not ZExtAttribute" set fixes the issue.
This fixes 197.parser but there is more to do. Any comparison and possibly
other operators involving arguments may need to correctly cast the parameter
before its use, depending on the sign of the operator.

Change the syntax for parameter attributes:
...
1. The @ sign is no longer necessary.
2. We now support "function attributes" as parameter attribute 0.
3. Instead of locating the return type attributes after the type of a
function result, they are now located after the function header's
closing paranthesis and before any alignment or section options.
4. The way has been prepared for a new "noreturn" function attribute but
there is no support for recognizing it in the lexer nor doing anything
with it if it does get set.
5. The FunctionType::getParamAttrsText method now has support for
returning multiple attributes. This required a change in its interface.
I'm unhappy that this change leads to 6 new shift/reduce conflicts, but
in each case bison's decision to choose the shift is correct so there
shouldn't be any damage from these conflicts.
