correct programs will not access memory at undefined addresses -- so it's not
worth the effort of doing anything more aggressive.

We need this so can not bake DESTDIR into the O'Caml symlinks.

These instructions technically define AL,AH, but a trick in X86ISelDAGToDAG
reads AX in order to avoid reading AH with a REX instruction.

Fix PR6489.

just count references to it from JIT output to decide when to destroy it.  This
patch waits to destroy the JIT's memory of a stub until the Function it refers
to is destroyed.  External function stubs and GVIndirectSyms aren't destroyed
until the JIT itself is.

Clang's support for weakref is now better than llvm-gcc's :-)

We don't introduce a new symbol and we correctly mark undefined references weak only if there is no
definition or regular undefined references in the same file.

Instruction (PLI) for disassembly only.

According to A8.6.120 PLI (immediate, literal), for example, different
instructions are generated for "pli [pc, #0]" and "pli [pc, #-0"].  The
disassembler solves it by mapping -0 (negative zero) to -1, -1 to -2, ..., etc.

  IF(condition(value)):
If the value satisfies the condition, the line is processed by lit;  otherwise
it is skipped.  A test with no unignored directives is resolved as Unsupported.

The test suite is responsible for defining conditions;  conditions are unary
functions over strings.  I've defined two conditions in the LLVM test suite,
TARGET (with values like those in TARGETS_TO_BUILD) and BINDING (with values
like those in llvm_bindings).  So for example you can write:
  IF(BINDING(ocaml)): RUN: %blah %s -o -
and the RUN line will only execute if LLVM was configured with the ocaml
bindings.

we now may have identical states with different analysis context.

Set the right AnalysisContext in state when entering and leaving a callee.

With both of the above changes, we can pass the test case.

transformation much more careful. Truncating binary '01' to '1' sounds like it's
safe until you realize that it switched from positive to negative under a signed
interpretation, and that depends on the icmp predicate.

Also a few miscellaneous cleanups.

Look ahead a bit to determine if a physical register def that is not marked dead is really alive. This is necessary to catch a lot of common cse opportunities for targets like x86.

exposes yet more factoring opportunitites, shrinking the X86 table 
to 79144 bytes.
