Each InterferenceCache::Cursor instance references a cache entry. A
non-zero reference count guarantees that the entry won't be reused for a
new register.

This makes it possible to have multiple live cursors examining
interference for different physregs.

The total number of live cursors into a cache must be kept below
InterferenceCache::getMaxCursors().

Code generation should be unaffected by this change, and it doesn't seem
to affect the cache replacement strategy either.

Fix up assertion in r135018 so it doesn't trigger on 32-bit; when we're in 32-bit, it doesn't matter whether the operation overflows because the computed address is not wider than the immediate.

Add logic to modify-python-lldb to correct swig's transformation of 'char **argv' and 'char **envp'
to 'char argv' and 'char envp' by morphing them into the 'list argv' and 'list envp' (as a list of
Python strings).

The cache entry referenced by the best split candidate could become
clobbered by an unsuccessful candidate.

The correct fix here is to use reference counts on the cache entries.

Flesh out the options supported for the instruction. Shuffle tests a bit and
add entries for the rest of the options. Add an alias to handle the default
operand of "sy".

Add a target-indepedent entry to MCInstrDesc to describe the encoded size of an opcode.  Switch ARM over to using that rather than its own special MCInstrDesc bits.

Use %feature("docstring") for methods of SBModule class so that the methods signature also gets generated in the Python docstring.

clang/gcc/llvm-gcc.  If the first breakpoint is due to stop at an inlined
frame, test that the call site corresponds to where it should be.  Also add
an expecr for a second break stop, if the first break stop corresponds to an
inlined call frame #0.

Make sure we don't combine a large displacement and a frame index in the same addressing mode on x86-64.  It can overflow, leading to a crash/miscompile.
