Summary:
An AArch64 LE relocation is a positive ("variant 1") offset. This
relocation is used to write the upper 12 bits of a 24-bit offset into an
add instruction:

    add x0, x0, :tprel_hi12:v1

The comment in the ARM docs for R_AARCH64_TLSLE_ADD_TPREL_HI12 is:

"Set an ADD immediate field to bits [23:12] of X; check 0 <= X < 2^24."

This change improves the performance of 376.kdtree by giving the compiler an
opportunity to do inlining and other optimizations for the call path,
__kmpc_omp_task_complete_if0()->__kmp_task_finish(), which is one of the hot
paths in the program; some functions in kmp_taskdeps.cpp were moved to the new
header file, kmp_taskdeps.h to achieve this.

This patch extends LoopInterchange to move LCSSA to the right place
after interchanging. This is required for LoopInterchange to become a
function pass.

An alternative to the manual moving of the PHIs, we could also re-form
the LCSSA phis for a set of interchanged loops, but that's more
expensive.

We now generate cttz with the zero_undef flag set to false. This allows -O0 to avoid the zero check.

llvm-svn: 343127

Previously we used a select and the zero_undef=true intrinsic. In -O2 this pattern will get optimized to zero_undef=false. But in -O0 this optimization won't happen. This results in a compare and cmov being wrapped around a tzcnt/lzcnt instruction.

By using the zero_undef=false intrinsic directly without the select, we can improve the -O0 codegen to just an lzcnt/tzcnt instruction.

Summary:
This is essentially NFC, because the complex pattern used for these patterns
will fail on non-CI, but this makes the pattern consistent with other CI
smrd patterns.  It is also a performance improvement, because the pattern
will now fail earlier on non-CI.
