For PR411:

This patch is an incremental step towards supporting a flat symbol table.
It de-overloads the intrinsic functions by providing type-specific intrinsics
and arranging for automatically upgrading from the old overloaded name to
the new non-overloaded name. Specifically:
llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64
llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64
llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64
llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64
llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64
New code should not use the overloaded intrinsic names. Warnings will be
emitted if they are used.

"All this should do is create what will eventually be the specialised

template specialisations' methods have been absorbed, patches
submitted method by method. I'll nuke the specialisations and have
the new objects inherit directly from passmanagert, and sanitise the

When moving constant entries in 'Map' if the entry is the representative
constant for the abstractypemap, make sure to update it as well. This

For large constants (e.g. arrays and structs with many elements) just

creating the keys and doing comparisons to index into 'Map' takes a lot

Split SimpleConstantVal up into its components, so each Constant subclass getsa different enum value. This allows 'classof' for these to be really simple,not needing to call getType() anymore.
...
This speeds up isa/dyncast/etc for constants, and also makes them smaller.
For example, the text section of a release build of InstCombine.cpp shrinks
from 230037 bytes to 216363 bytes, a 6% reduction.
