capacity and remove the workaround in SmallVector<T,0>.  There are some
theoretical benefits to a N->2N+1 growth policy anyway.

Move decoding of insertps back to avoid unused warnings in x86 isel lowering, and fix movlhps/movhlps to decode 4 elements shuffles

there are clearly no stores between the load and the store. This fixes
this miscompile reported as PR7833.

This breaks the test/CodeGen/X86/narrow_op-2.ll optimization, which is
safe, but awkward to prove safe. Move it to X86's README.txt.

Move x86 specific shuffle mask decoding to its own header, it's also going to be used elsewhere. Also trim trailing whitespaces

Minix apparently doesn't like double-slash separators, and there's
no apparent need for them here.

Fix a bug in LazyValueInfo that CorrelatedValuePropagation exposed: In the LVI lattice, undef and the full set ConstantRange should not
be treated as equivalent.

Added support for register allocators to record which intervals are spill intervals, and where the uses and defs of the original intervals were in the original code.

Spill intervals can be hidden using the "-rmf-intervals=virt-nospills*" option.

I'm sure it is harmless.  Original commit message:
If PrototypeValue is erased in the middle of using the SSAUpdator
then the SSAUpdator may access freed memory.  Instead, simply pass
in the type and name explicitly, which is all that was used anyway.
