d9e5c764bf Freeze reserved registers before starting register allocation. 
The register allocators don't currently support adding reserved
registers while they are running.  Extend the MRI API to keep track of
the set of reserved registers when register allocation started.

Target hooks like hasFP() and needsStackRealignment() can look at this
set to avoid reserving more registers during register allocation.

ce16339930 The powers that be have decided that LLVM IR should now support 16-bit 
"half precision" floating-point with a first-class type.

This patch adds basic IR support (but not codegen support).

f5bb45f895 Note ARM constant island alignment in the release notes. 
The command line option should be removed, but not until the feature has
gotten a lot of testing. The ARMConstantIslandPass tends to have subtle
bugs that only show up after a while.

e1a2984847 Fix a subtle semantic issue with poison values that came up in 
recent discussions. Poison can't make every value that depends on
it act in maximally undefined ways, because the optimizer may still
hoist code following the usual rules for undef. Make Poison invoke
its full undefined behavior only when it reaches an instruction with
externally visible side effects.
