bpf: remove unnecessary truncate operation

For networking-type bpf program, it often needs to access
packet data. A context data structure is provided to the bpf
programs with two fields:
        u32 data;
        u32 data_end;
User can access these two fields with ctx->data and ctx->data_end.
During program verification process, the kernel verifier modifies
the bpf program with loading of actual pointer value from kernel
data structure.
    r = ctx->data      ===> r = actual data start ptr
    r = ctx->data_end  ===> r = actual data end ptr

A typical program accessing ctx->data like
    char *data_ptr = (char *)(long)ctx->data
will result in a 32-bit load followed by a zero extension.
Such an operation is combined into a single LDW in DAG combiner
as bpf LDW does zero extension automatically.

In cases like the below (which can be a result of global value numbering
and partial redundancy elimination before insn selection):
B1:
   u32 a = load-32-bit &ctx->data
   u64 pa = zext a

Android.rules: build x86 tests with -mstackrealign

All android builds systems have switched to -mstackrealign for building
x86 binaries, so follow their cue with our mini build system.

This presently breaks just one test (TestReturnValue), and this is due
to a compiler bug, which has already been fixed in clang, but it hasn't
made it yet into the official NDK compiler. While I'm touching that
test, I also remove an android-specific XFAIL, which is not relevant
anymore.

LLVM/llvm 306681llvm/trunk/test/Transforms/InstCombine memset.ll

Restore original intent of memset instcombine test

Summary:
The original intent of test/Transforms/InstCombine/memset.ll was to test for lowering of 
llvm.memset into stores when the size of the memset is 1, 2, 4, or 8. Sometime between 
then and now the test has stopped testing for that, but remained passing due to testing 
for the absence of llvm.memset calls rather than the presence of store instructions. Right 
now this test ends up with an empty function body because the alloca is eliminated as 
safe-to-remove, which results in the llvm.memset calls's being eliminated due to their 
pointer args being undef; so it is not testing for conversion of llvm.memset into store 
instructions at all.

This change alters the test to verify that store instructions are created, and moves the 
target of the memset to an arg of the proc to avoid it being eliminated as unused.

Recommit "[Support] Add RetryAfterSignal helper function"

The difference from the previous version is the use of decltype, as the
implementation of std::result_of in libc++ did not work correctly for
variadic function like open(2).

Original summary:
This function retries an operation if it was interrupted by a signal
(failed with EINTR). It's inspired by the TEMP_FAILURE_RETRY macro in
glibc, but I've turned that into a template function. I've also added a
fail-value argument, to enable the function to be used with e.g.
fopen(3), which is documented to fail for any reason that open(2) can
fail (which includes EINTR).

The main user of this function will be lldb, but there were also a
couple of uses within llvm that I could simplify using this function.

[UnwindAssembly/x86] Add support for "lea imm(%ebp), %esp" pattern

Summary:
The instruction pattern:
and $-16, %esp
sub $imm, %esp
...
lea imm(%ebp), %esp

appears when the compiler is realigning the stack (for example in
main(), or almost everywhere with -mstackrealign switch). The "and"
instruction is very difficult to model, but that's not necessary, as
these frames are always %ebp-based (the compiler also needs a way to
restore the original %esp). Therefore the plans we were generating for
these function were almost correct already. The only place we were doing
it wrong were the last instructions of the epilogue (usually just
"ret"), where we had to revert to %esp-based unwinding, as the %ebp had
been popped already.

This was wrong because our "distance of esp from cfa" counter had picked
up the "sub" instruction (and incremented the counter) but it had not
seen that the register was reset by the "lea" instruction.

This patch fixes that shortcoming, and adds a test for handling
functions like this.

[lit] Re-apply: Fix some convoluted logic around Unicode encoding, and de-duplicate across 
modules that used it.

(Take 2: this patch re-applies r306625, which was reverted in r306629. This
patch includes only trivial fixes.)

In Python2 and Python3, the various (non-)?Unicode string types are sort of
spaghetti. Python2 has unicode support tacked on via the 'unicode' type, which
is distinct from 'str' (which are bytes). Python3 takes the "unicode-everywhere"
approach, with 'str' representing a Unicode string.

Both have a 'bytes' type. In Python3, it is the only way to represent raw bytes.
However, in Python2, 'bytes' is an alias for 'str'. This leads to interesting
problems when an interface requires a precise type, but has to run under both
Python2 and Python3.

The previous logic appeared to be correct in all cases, but went through more
layers of indirection than necessary. This change does the necessary conversions
in one shot, with documentation about which paths might be taken in Python2 or
Python3.

Changes from r306625: some tests just print binary outputs, so in those cases,
fall back to str() in Python3. For googletests, add one missing call to
to_string().
