Fix TestAttachResume test so it doesn't hang on Linux with ptrace lockdown.
Similar to previous fix, this augments the test inferior to
immediately indicate it may be ptraced by any Linux process

This seems to indicate we need to fix our lldb attach logic to
catch when an attach fails, and trigger an appropriate error

Add an option to the LTO code generator to disable vectorization during LTO
We used to always vectorize (slp and loop vectorize) in the LTO pass pipeline.
r220345 changed it so that we used the PassManager's fields 'LoopVectorize' and
'SLPVectorize' out of the desire to be able to disable vectorization using the
cl::opt flags 'vectorize-loops'/'slp-vectorize' which the before mentioned
fields default to.
Unfortunately, this turns off vectorization because those fields
default to false.
This commit adds flags to the LTO library to disable lto vectorization which
reconciles the desire to optionally disable vectorization during LTO and
the desired behavior of defaulting to enabled vectorization.
We really want tools to set PassManager flags directly to enable/disable
vectorization and not go the route via cl::opt flags *in*
PassManagerBuilder.cpp.

Fix HelloWorld attach test for Linux kernels with ptrace ancestor lockdown.
Similar to a recent test I fixed for gdb-remote attach scenarios, this
fix is for Linux kernels, such as Ubuntu's stock setup on 11.04-ish and
later, where ptrace starts requiring a ptracer to be an ancestor of the
inferior to be ptraced. This change checks for Linux and the ptrace-related
flags. If they're found, it tries to switch on the "allow any ptracer" mode
for the inferior as the first statements in the program. It's a best-effort
solution - if the prctl call fails, the failure is ignored, and probably will
lead to the test failing.
The ptrace security behavior can be modified system-wide, but is outside the
scope of the test to address. Hence I went with this particular solution.

Don't ever call materializeAllPermanently during LTO.
To do this, change the representation of lazy loaded functions.
The previous representation cannot differentiate between a function whose body
has been removed and one whose body hasn't been read from the .bc file. That
means that in order to drop a function, the entire body had to be read.

Use rsqrt (X86) to speed up reciprocal square root calcs
This is a first step for generating SSE rsqrt instructions for
reciprocal square root calcs when fast-math is allowed.
For now, be conservative and only enable this for AMD btver2
where performance improves significantly - for example, 29%
on llvm/projects/test-suite/SingleSource/Benchmarks/BenchmarkGame/n-body.c
(if we convert the data type to single-precision float).
This patch adds a two constant version of the Newton-Raphson
refinement algorithm to DAGCombiner that can be selected by any target
via a parameter returned by getRsqrtEstimate()..

[mips] Replace MipsABIEnum with a MipsABIInfo class.
Summary:
No functional change yet, it's just an object replacement for an enum.
It will allow us to gather ABI information in a single place so that we can
start testing for properties of the ABI's instead of the ABI itself.
For example we will eventually be able to use:
ABI.MinStackAlignmentInBytes()
instead of:
(isABI_N32() || isABI_N64()) ? 16 : 8
which is clearer and more maintainable.
