564f193ad0 Make StoreValueToMemory a little more efficient by not copying a 
GenericValue to a temporary.

b5e0b0bc5e Make GenericeValue into a struct with a union instead of just a union. This 
allows an APInt value to be constructed. Remove all the native integer types
from the union. These are replaced with the single IntVal of type APInt.

e4da6fa801 Use std::deque to manage loop queue inside LPPassManager.

45343b04b3 Keep track of inherited analysis. For example, if a loop pass does not 
preserve dominator info then it should update parent FPPassManager's
available analysis info to reflect this.

edbde240be Add preparePassManager() hook. This allows each pass to check whether 
current active pass manager is appropriate or not.

A loop pass may consider current LPPassManager in appropraite if loop
pass is not preserving analysis information that is used by other
passes managed by current LPPassManager. In such situation, loop pass
can pop current LPPassManager from the PMStack using this  hook
and use new LPPassManager for itself.

5ecf7f6214 Document the use of getValueType() more accurately, specifically explain 
that the instruction opcode is added to the InstructionVal value and the
consequences of that.

79495d839e Current pass manager, not the parent pass manager, assumes the role of 
last user when one of the managed pass uses info provided by parent pass
manager.

This was exposed by LPPassManager work.

cdb5aa2805 Make the creation functions take an error string. This will help the 
ExecutionEngine report errors on creation (like bytecode stuff) and also
help to get rid of exception handling.

53a673b3ed Add a non-virtual test for zero, isZero, and rename isUnitValue isOne. 
These will be used in upcoming patches to avoid virtual function call when
the client knows it is a ConstantInt.

2ce72a4bd8 Add an isUnitValue method for comparison against 1. This just follows a 
common pattern with isNullValue, isAllOnesValue, etc. It also helps to
prevent things like getZExtValue() == 1, which could assert for large
bitwidths.
