95ec62ccf1 Add missing function CreateFPCast to the TargetFolder. It's there in the other 
folders and not having it here fails to compile if you actually try to use it.

Also, CreatePointerCast was failing to do the part where it does TD-aware
constant folding. Granted there is exactly one case where that it will ever
do anything, but there's no reason to skip it. For reference, that case is a
subtraction between two constant offsets on the same global variable, eg.,
"&A[123] - &A[4].f".

8a18a7b5f5 Buildbot Fix. 
This method can be called with a '0' argument which checks the return
value. However, the method it calls doesn't expect '0' as a valid value. Call the
correct method when it's 0.

814c41e2c5 Initial commit for the AttributesImpl class. 
This opaque class will contain all of the attributes. All attribute queries will
go through this object. This object will also be uniqued in the LLVMContext.
Currently not used, so no implementation change.

270e075dec TargetLowering interface to set/get minimum block entries for jump tables. 
Provide interface in TargetLowering to set or get the minimum number of basic
blocks whereby jump tables are generated for switch statements rather than an
if sequence.

    getMinimumJumpTableEntries() defaults to 4.
    setMinimumJumpTableEntries() allows target configuration.

    This patch changes the default for the Hexagon architecture to 5
    as it improves performance on some benchmarks.

f8bd27333f Casting: assert that pointer arguments to isa<> are non-null. 
This silences several analyzer warnings within LLVM, and provides a slightly
nicer crash experience when someone calls isa<>, cast<>, or dyn_cast<> with
a null pointer.

135898ebe3 ARM: Use a dedicated intrinsic for vector bitwise select. 
The expression based expansion too often results in IR level optimizations
splitting the intermediate values into separate basic blocks, preventing
the formation of the VBSL instruction as the code author intended. In
particular, LICM would often hoist part of the computation out of a loop.

46c3ebc1a6 Implement a correct copy constructor for Record. Now that we're using the ID number as a key in maps (for determinism), it is imperative that ID numbers be globally unique, even when we copy construct a Record. 
This fixes some obscure failure cases involving registers defined inside multiclasses or foreach constructs that would not receive a unique ID, and would end up being omitted from the AsmMatcher tables.
