tantalyzing enough that people keep trying to use it.

66fd0f6b4b Remove this test because it checks wheter optimizer handled @llvm.dbg.global_variable appropriately or not. LLVM does not use this scheme to encode debug info for global variables any more.

4853c9c8d1 Remove test to check bugfix in handing debug info for global variables using intrinsics. Now, debug info for global variable is encoded using metadata. The old code path is now history and there is no need to have a test to check a bug fix in old code path.

19b59d2278 Emit type checks late instead of early, this encourages 
structural matching code to be factored and shared this
shrinks the X86 isel table from 86537 to 83890 bytes.

4baff2da00 Emit a redundant check for immediates at root context, e.g. (imm 0). 
This allows formation of OpcodeSwitch for top level patterns, in
particular on X86.  This saves about 1K of data space in the x86
table and makes the dispatch much more efficient.

cdfa80eaaf eliminate the CheckMultiOpcodeMatcher code and have each 
ComplexPattern at the root be generated multiple times, once
for each opcode they are part of.  This encourages factoring
because the opcode checks get treated just like everything
else in the matcher.

8529ea0237 add a new OPC_SwitchOpcode which is semantically equivalent 
to a scope where every child starts with a CheckOpcode, but
executes more efficiently.  Enhance DAGISelMatcherOpt to 
form it.

This also fixes a bug in CheckOpcode: apparently the SDNodeInfo
objects are not pointer comparable, we have to compare the
enum name.

a3ca8f3e2d pull MarkFlagResult out from between an EmitNode/CompleteMatch 
pair.  This encourages MorphNodeTo formation, this gets us 200
more MorphNodeTo's on X86 and shrinks the table a bit.

17b56423d9 Emit redundant opcode checks for andimm and orimm tests at root 
so that we get grouping at the top level.

Add an optimization to reorder type check & record nodes
after opcode checks.  We prefer to expose tree shape 
matching which improves grouping and will enhance the next
optimization.

ac55b2ddbc inline the node transforms and node predicates into the generated 
dispatcher method.  This eliminates the dependence of the new isel's
generated code on the old isel's predicates, however some random
hand written isel code still uses them.
