Andrew Trick 3ca3f98c2c SCEV: Added a data structure for storing not-taken info per loop 
exit. Added an interfaces for querying either the loop's exact/max
backedge taken count or a specific loop exit's not-taken count.

Duncan Sands c1c92719a4 Add helper function for getting true/false constants in a uniform 
way for i1 and vector of i1 types.  Use these to make some code
more self-documenting.

Devang Patel 8fb9fd6769 There are two ways to map a variable to its lexical scope. Lexical scope information is embedded in MDNode describing the variable. It is also available as a part of DebugLoc attached with DBG_VALUE instruction. DebugLoc attached with an instruction is less reliable in optimized code so use information embedded in the MDNode.

Dan Gohman a293f24a0d Teach IVUsers to stop at non-affine expressions unless they are both 
outside the loop and reducible.

This more completely hides them from LSR, which isn't usually able to
do anything meaningful with non-affine expressions anyway, and this
consequently hides them from SCEVExpander, which is acutely unprepared
for non-affine expressions.

Replace test/CodeGen/X86/lsr-nonaffine.ll with a new test that tests
the new behavior.

This works around the bug in PR10117 / rdar://problem/9633149, and is
generally an improvement besides.

Dylan Noblesmith 3595357772 Support: make floating-exception header private 
It has only one user. This eliminates the last include of
config.h from the public headers -- ideally, config.h
shouldn't even be installed by `make install` anymore.

Chris Lattner cc19efaa97 Revamp the "ConstantStruct::get" methods. Previously, these were scattered 
all over the place in different styles and variants.  Standardize on two
preferred entrypoints: one that takes a StructType and ArrayRef, and one that
takes StructType and varargs.

In cases where there isn't a struct type convenient, we now add a
ConstantStruct::getAnon method (whose name will make more sense after a few
more patches land).  

It would be "really really nice" if the ConstantStruct::get and 
ConstantVector::get methods didn't make temporary std::vectors.
