8333730259 build/Make & CMake: Pass the appropriate --native-target and --enable-targets
options to llvm-build, so the all-targets etc. components are defined properly.

affc6cf9d2 llvm-build: Add --native-target and --enable-targets options, and add logic to
handle defining the "magic" target related components (like native,
nativecodegen, and engine).
 - We still require these components to be in the project (currently in
   lib/Target) so that we have a place to document them and hopefully make it
   more obvious that they are "magic".

6852b69e15 llvm-build: Change CBackend and CppBackend to not use library_name. This will
change the generated library .a file name once we fully switch over, but
simplifies how we treat these targets without requiring more special casing
(since their library group name and the codegen library name currently map to
the same "llvm-config" style component name).

17afb06648 Strip old implicit operands after foldMemoryOperand.
The TII.foldMemoryOperand hook preserves implicit operands from the
original instruction.  This is not what we want when those implicit
operands refer to the register being spilled.

Implicit operands referring to other registers are preserved.

This fixes PR11347.

5ccb0825ed DeadStoreElimination can now trim the size of a store if the end of the store is dead.
Currently checks alignment and killing stores on a power of 2 boundary as this is likely
to trim the size of the earlier store without breaking large vector stores into scalar ones.

ef0b3ca3a8 Speculatively revert commit 144124 (djg) in the hope that the 32 bit
dragonegg self-host buildbot will recover (it is complaining about object
files differing between different build stages).  Original commit message:

Add a hack to the scheduler to disable pseudo-two-address dependencies in
basic blocks containing calls. This works around a problem in which
these artificial dependencies can get tied up in calling seqeunce
scheduling in a way that makes the graph unschedulable with the current
approach of using artificial physical register dependencies for calling
sequences. This fixes PR11314.

f4c4768fb2 Collapse DomainValues across loop back-edges.
During the initial RPO traversal of the basic blocks, remember the ones
that are incomplete because of back-edges from predecessors that haven't
been visited yet.

After the initial RPO, revisit all those loop headers so the incoming
DomainValues on the back-edges can be properly collapsed.

This will properly fix execution domains on software pipelined code,
like the included test case.

dbc372f47e Link to the live DomainValue after merging.
When merging two uncollapsed DomainValues, place a link to the active
DomainValue from the passive DomainValue.  This allows old stale
references to the passive DomainValue to be updated to point to the
active DomainValue.

The new resolve() function finds the active DomainValue and updates the
pointer.

This change makes old live-out lists more useful since they may contain
uncollapsed DomainValues that have since been merged into other
DomainValues.

ad6eef4a65 This patch handles unaligned loads and stores in Mips JIT. Mips backend
implements unaligned loads and stores with assembler macro-instructions
ulw, usw, ulh, ulhu, ush, and this patch emits corresponding instructions
instead of these macros. Since each unaligned load/store is expanded
into two corresponding loads/stores where offset for second load/store is
modified by +3 (for words) or +1 (for halfwords).
