Chris Lattner b6db2c6b31 Rearrange handling of jump tables. Highlights: 
1. MachineJumpTableInfo is now created lazily for a function the first time
   it actually makes a jump table instead of for every function.
2. The encoding of jump table entries is now described by the
   MachineJumpTableInfo::JTEntryKind enum.  This enum is determined by the
   TLI::getJumpTableEncoding() hook, instead of by lots of code scattered
   throughout the compiler that "knows" that jump table entries are always
   32-bits in pic mode (for example).
3. The size and alignment of jump table entries is now calculated based on
   their kind, instead of at machinefunction creation time.

Future work includes using the EntryKind in more places in the compiler,
eliminating other logic that "knows" the layout of jump tables in various
situations.

Chris Lattner a14ac3fd80 prep work to support a future where getJumpTableInfo will return 
a null pointer for functions with no jump tables.  No functionality
change.

Chris Lattner 3072add73c add a method to get the alignment of an integer type even 
when we don't have one laying around.  Useful if you don't
have an llvmcontext handy.

Bob Wilson fc060e4337 Change Value::getUnderlyingObject to have the MaxLookup value specified as a 
parameter with a default value, instead of just hardcoding it in the
implementation.  The limit of MaxLookup = 6 was introduced in r69151 to fix
a performance problem with O(n^2) behavior in instcombine, but the scalarrepl
pass is relying on getUnderlyingObject to go all the way back to an AllocaInst.
Making the limit part of the method signature makes it clear that by default
the result is limited and should help avoid similar problems in the future.
This fixes pr6126.
