Generate better select code by allowing the target to use scalar select, and not sign-extend.

Rename ANDROIDEABI to Android.

Most of the code guarded with ANDROIDEABI are not
ARM-specific, and having no relation with arm-eabi.
Thus, it will be more natural to call this
environment "Android" instead of "ANDROIDEABI".

Note: We are not using ANDROID because several projects
are using "-DANDROID" as the conditional compilation
flag.

LoopRotation: Make the brute force DomTree update more brute force.

We update until we hit a fixpoint. This is probably slow but also
slightly simplifies the code. It should also fix the occasional
invalid domtrees observed when building with expensive checking.

I couldn't find a case where this had a measurable slowdown, but
if someone finds a pathological case where it does we may have
to find a cleverer way of updating dominators here.

Thanks to Duncan for the test case.

Not all targets have efficient ISel code generation for select instructions.
For example, the ARM target does not have efficient ISel handling for vector
selects with scalar conditions. This patch adds a TLI hook which allows the
different targets to report which selects are supported well and which selects
should be converted to CF duting codegen prepare.

[ms-inline asm] Expose the Kind and Opcode variables from the
MatchInstructionImpl() function.

These values are used by the ConvertToMCInst() function to index into the
ConversionTable.  The values are also needed to call the GetMCInstOperandNum()
function.

Fix more fallout from r158919, similar to PR13547.

This code used to only handle malloc-like calls, which do not read memory.
r158919 changed it to check isNoAliasFn(), which includes strdup-like and
realloc-like calls, but it was not checking for dependencies on the memory
read by those calls.
