d1f94e90fd These two tests check whether oprimizer safely ignores @llvm.dbg.stoppoint intrinsic or not. This intrinsic is not used anymore.

81607c902f This test checks whether LICM ignores @llvm.dbg.stoppoint intrinsics appropriately or not. Now, llvm does not use this intrinsic. Remove this test.

60c0e37afc 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.

bd8965a7d9 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.

fa342faef9 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.

eb66921adb 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.

c99b5a25bb 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.

e9eeda878b 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.

4d0c931ba7 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.

out the old one next.
