Fix a crash when generating forward jumps to labels at very high assembly offsets
...
The first jump to a specific label was marked as jump to absolute
position -4. This value was stored in the assembly as a branch to a
offset (-4 - (instruction offset + 8)). The offset is only 24 bit
long on ARM. Thus instruction offsets higher than 2^23 - 12 would overflow
the offset.
Fix by denoting the first jump to a label by storing the jump
instruction location as the target. This will result in offset of -8,
which of course always fits in the branch instruction.

Remove elements transitions from the transition array.
...
This is preparatory work for reordering the transition tree. Since elements transitions will be at the root of the transition tree, runtime access to them is slow since we have to walk the transition tree backwards first. Hence remove the optimization that promoted them to a special field, requiring a pointer (mostly NULL) in every non-simple transition array.

Fix HType handling for HConstant with external references.

We cannot use set_type() with HType::None() in the HConstant
constructor, since set_type() asserts that the new type is a
subtype of the previous one, but HType::None() is not a subtype
of HType::Tagged() which is the initial type set by the HValue
constructor.
This patch adds an optional type parameter to the HValue,
HInstruction and HTemplateInstruction constructors.
