ce718ff9f4 Extend the IL for selecting TLS models (PR9788) 
This allows the user/front-end to specify a model that is better
than what LLVM would choose by default. For example, a variable
might be declared as

  @x = thread_local(initialexec) global i32 42

if it will not be used in a shared library that is dlopen'ed.

If the specified model isn't supported by the target, or if LLVM can
make a better choice, a different model may be used.

7806c0778f Teach LiveVariables to handle <undef> operands. 
It's simple: Don't treat <undef> operands as uses, and don't assume a
virtual register has a defining instruction unless a real use has been
seen.

fc47253294 (sub X, imm) gets canonicalized to (add X, -imm) 
There are patterns to handle immediates when they fit in the immediate field.
e.g. %sub = add i32 %x, -123
=>   sub r0, r0, #123
Add patterns to catch immediates that do not fit but should be materialized
with a single movw instruction rather than movw + movt pair.
e.g. %sub = add i32 %x, -65535
=>   movw r1, #65535
     sub r0, r0, r1

70c9bf3c1a ARM: Add a better diagnostic for some out of range immediates. 
As an example of how the custom DiagnosticType can be used to provide
better operand-mismatch diagnostics, add a custom diagnostic for
the imm0_15 operand class used for several system instructions.
Update the tests to expect the improved diagnostic.

4dbfdfba6c TableGen: AsmMatcher support for better operand diagnostics. 
"Invalid operand" may be a completely correct diagnostic, but it's often
insufficiently specific to really help identify and fix the problem in
assembly source. Allow a target to specify a more-specific diagnostic kind
for each AsmOperandClass derived definition and use that to provide
more detailed diagnostics when an operant of that class resulted in a
match failure.

    This will be needed for some upcoming PowerPC itineraries.

Performance optimizations:
- SwitchInst: case values stored separately from Operands List. It allows to make faster access to individual case value numbers or ranges.
- Optimized IntItem, added APInt value caching.
- Optimized IntegersSubsetGeneric: added optimizations for cases when subset is single number or when subset consists from single numbers only.
