The x64 ABI has two major function types:
 - frame functions
 - leaf functions

A frame function is one which requires a stack frame.  A leaf function
is one which does not.  A frame function may or may not have a frame
pointer.

A leaf function does not require a stack frame and may never modify SP
except via a return (RET, tail call via JMP).

A frame function which has a frame pointer is permitted to use the LEA
instruction in the epilogue, a frame function without which doesn't
establish a frame pointer must use ADD to adjust the stack pointer epilogue.

[LV] Don't mark pointers used by scalarized memory accesses uniform

Previously, all consecutive pointers were marked uniform after vectorization.
However, if a consecutive pointer is used by a memory access that is eventually
scalarized, the pointer won't remain uniform after all. An example is
predicated stores. Even though a predicated store may be consecutive, it will
still be scalarized, making it's pointer operand non-uniform.

This patch updates the logic in collectLoopUniforms to consider the cases where
a memory access may be scalarized. If a memory access may be scalarized, its
pointer operand is not marked uniform. The determination of whether a given
memory instruction will be scalarized or not has been moved into a common

mapping a yaml field to an object in code has always been
a stateless operation.  You could still pass state by using the
`setContext` function of the YAMLIO object, but this represented
global state for the entire yaml input.  In order to have
context-sensitive state, it is necessary to pass this state in
at the granularity of an individual mapping.

This patch adds support for this type of context-sensitive state.
You simply pass an additional argument of type T to the
`mapRequired` or `mapOptional` functions, and provided you have
specialized a `MappingContextTraits<U, T>` class with the

DependenceInfo: Make clear that no double-free problem exists

When running the clang static analyser to check for memory issues, this code
originally showed a double free, as the analyser was unable to understand that
isl_union_map_free always returns NULL and consequently later uses of the isl
object we just freed will never be reached. Without this knowledge, the analyser
has to issue a warning.

We refactor the code to make it clear that for empty maps the current loop
iteration is aborted.

Compute section names only once.

This simplifies error handling as there is now only one place in the
code that needs to consider the possibility that the name is
corrupted. Before we would do it in every access.

I mised the check that it had to support ARM to work. This commit tries
to fix that, to make sure we don't emit ARM code in Thumb-only mode.

The switch coveres all possible values. If a new one is added in the

the switch needs updating.
