Suspend program threads before sending the SIGSTOP & resuming, so other threads won't get into trouble while we are waiting for the SIGSTOP.

- FlatArrayMap. Very simple map container that uses flat array inside.
- MultiImplMap. Map container interface, that has two modes, one for small amount of elements and one for big amount.
- SmallMap. SmallMap is DenseMap compatible MultiImplMap. It uses FlatArrayMap for small mode, and DenseMap for big mode. 

Also added unittests for new classes and update for ProgrammersManual.
For more details about new classes see ProgrammersManual and comments in sourcecode.

This function is only used for a heuristic during -join-physregs. It
doesn't need floating point.

Cross-class joins have been normal and fully supported for a while now.
With TableGen generating the getMatchingSuperRegClass() hook, they are
unlikely to cause problems again.

llvm-svn: 155552

Remove the heuristic for disabling cross-class joins. The greedy
register allocator can handle the narrow register classes, and when it
splits a live range, it can pick a larger register class.

Benchmarks were unaffected by this change.

Add ifdef around getSubtargetFeatureName in tablegen output file so that only targets that want the function get it. This prevents other targets from getting an unused function warning.

Use vector_shuffles instead of target specific unpack nodes for AVX ZERO_EXTEND/ANY_EXTEND combine. These will be converted to target specific nodes during lowering. This is more consistent with other code.

Ensure that lldb/runtime is not a dead point in the Python package hierarchy - This is a first preliminary step in fixing data formatters after Greg's changes to the Python resources on-disk layout
