bc227b65c2 Change a very hot piece of code in TableGen's register unit computations to use bit vectors rather than arrays.
For target descriptions with very large and very dense register files, TableGen
can take an extremely long time to run.  This change makes a dent in that (~15%
in my measurements) by accelerating the single hottest operation with better data
structures.

I believe there's still a lot of room to make this even faster with more global
changes that require replacing some of the existing datastructures in this area
with bit vectors, but that's a more involved change and I wanted to get this
simpler improvement in first.

e7769db118 [LoopVectorize] Induction variables: support arbitrary constant step.
Previously, only -1 and +1 step values are supported for induction variables. This patch extends LV to support
arbitrary constant steps.
Initial patch by Alexey Volkov. Some bug fixes are added in the following version.

6953381b0c [LTO] Scan all per-function subtargets when collecting runtime library names.
accumulateAndSortLibcalls in LTOCodeGenerator.cpp collects names of runtime
library functions which are used to identify user-defined functions that should
be protected. Previously, this function would only scan the TargetLowering
object belonging to the "main" subtarget for the library function names. This
commit changes it to scan all per-function subtargets.

c9fbc97e95 x86: Fix large model calls to __chkstk for dynamic allocas
In the large code model, we now put __chkstk in %r11 before calling it.

Refactor the code so that we only do this once. Simplify things by using
__chkstk_ms instead of __chkstk on cygming. We already use that symbol
in the prolog emission, and it simplifies our logic.

Second half of PR18582.

370056ca5d [LPM] Remove a PPC64 hack to try to work around a bad interaction
between the linker's TLS optimizations and Clang's TLS code generation.

For now, Clang has been changed to disable linker TLS optimizations
until it (and LLVM more generally) are emitting TLS code sequences
compatible with the old bugs found in the linkers. That's a better fix
to handle bootstrapping on that platform.

3eb64280e1 [LoopReroll] Alter the data structures used during reroll validation.
The validation algorithm used an incremental approach, building each
iteration's data structures temporarily, validating them, then
adding them to a global set.

This does not scale well to having multiple sets of Root nodes, as the
set of instructions used in each iteration is the union over all
the root nodes. Therefore, refactor the logic to create a single, simple
container to which later logic then refers. This makes it simpler
control-flow wise to make the creation of the container more complex with
the addition of multiple root sets.

26c81cc870 [GVN] don't propagate equality comparisons of FP zero (PR22376)
In http://reviews.llvm.org/D6911, we allowed GVN to propagate FP equalities
to allow some simple value range optimizations. But that introduced a bug
when comparing to -0.0 or 0.0: these compare equal even though they are not
bitwise identical.

This patch disallows propagating zero constants in equality comparisons.
