[fast-isel] SelectInsertValue seems to be causing miscompiles for ARM.  Disable while I investigate.

Move isUnpredicatedTerminator() default implementation to TargetInstrInfoImpl to break Target's dependency on CodeGen.

Enhance both TargetLibraryInfo and SelectionDAGBuilder so that the latter can use the former to prevent the formation of libm SDNode's when  -fno-builtin is passed.

Filter "sink to" candidate blocks sooner. This avoids unnecessary computation to determine whether the block dominates all uses or not.

llvm-svn: 146184

Teach SelectionDAG to match more calls to libm functions onto existing SDNodes.  Mark these nodes as illegal by default, unless the target declares otherwise.

clients to decide whether to look inside bundled instructions and whether
the query should return true if any / all bundled instructions have the
queried property.

We must not issue a bitcast operation for integer-promotion of vector types, because the
location of the values in the vector may be different.

Make sure we correctly set LiveRegGens when a call is unscheduled.  <rdar://problem/10460321>.  No testcase because this is very sensitive to scheduling.

generator to it. For non-bundle instructions, these behave exactly the same
as the MC layer API.

For properties like mayLoad / mayStore, look into the bundle and if any of the
bundled instructions has the property it would return true.
For properties like isPredicable, only return true if *all* of the bundled
instructions have the property.
For properties like canFoldAsLoad, isCompare, conservatively return false for
bundles.

Zap unnecessary isIntDivCheap() check.  PR11485.  No testcase because this doesn't affect any in-tree target.

This flag is used when bundling machine instructions.  It indicates
whether the operand reads a value defined inside or outside its bundle.

1. Added opcode BUNDLE
2. Taught MachineInstr class to deal with bundled MIs
3. Changed MachineBasicBlock iterator to skip over bundled MIs; added an iterator to walk all the MIs
4. Taught MachineBasicBlock methods about bundled MIs

This was actually a bit of a mess. TLI.setPrefLoopAlignment was clearly
documented as taking log2(bytes) units, but the x86 target would still
set a preferred loop alignment of '16'.

CodePlacementOpt passed this number on to the basic block, and
AsmPrinter interpreted it as bytes.

Now both MachineFunction and MachineBasicBlock use logarithmic
alignments.

Obviously, MachineConstantPool still measures alignments in bytes, so we
can emulate the thrill of using as.
