Feeding isSafeToSpeculativelyExecute its DataLayout pointer
isSafeToSpeculativelyExecute can optionally take a DataLayout pointer. In the
past, this was mainly used to make better decisions regarding divisions known
not to trap, and so was not all that important for users concerned with "cheap"
instructions. However, now it also helps look through bitcasts for

[mips] Add support for -modd-spreg/-mno-odd-spreg
Summary:
When -mno-odd-spreg is in effect, 32-bit floating point values are not
permitted in odd FPU registers. The option also prohibits 32-bit and 64-bit
floating point comparison results from being written to odd registers.
This option has three purposes:
* It allows support for certain MIPS implementations such as loongson-3a that
do not allow the use of odd registers for single precision arithmetic.
* When using -mfpxx, -mno-odd-spreg is the default and this allows us to
statically check that code is compliant with the O32 FPXX ABI since mtc1/mfc1
instructions to/from odd registers are guaranteed not to appear for any
reason. Once this has been established, the user can then re-enable
-modd-spreg to regain the use of all 32 single-precision registers.
* When using -mfp64 and -mno-odd-spreg together, an O32 extension named
O32 FP64A is used as the ABI. This is intended to provide almost all
functionality of an FR=1 processor but can also be executed on a FR=0 core
with the assistance of a hardware compatibility mode which emulates FR=0
behaviour on an FR=1 processor.
* Added '.module oddspreg' and '.module nooddspreg' each of which update
the .MIPS.abiflags section appropriately
* Moved setFpABI() call inside emitDirectiveModuleFP() so that the caller
doesn't have to remember to do it.
* MipsABIFlags now calculates the flags1 and flags2 member on demand rather
than trying to maintain them in the same format they will be emitted in.
There is one portion of the -mfp64 and -mno-odd-spreg combination that is not
implemented yet. Moves to/from odd-numbered double-precision registers must not
use mtc1. I will fix this in a follow-up.

On MIPS32r6/MIPS64r6, floating point comparisons return 0 or -1 but integer

Updated the various uses of getBooleanContents. Two simplifications had to be
disabled when float and int boolean contents differ:
- ScalarizeVecRes_VSELECT except when the kind of boolean contents is trivially
discoverable (i.e. when the condition of the VSELECT is a SETCC node).
- visitVSELECT (select C, 0, 1) -> (xor C, 1).
Come to think of it, this one could test for the common case of 'C'
being a SETCC too.
Preserved existing behaviour for all other targets and updated the affected
MIPS32r6/MIPS64r6 tests. This also fixes the pi benchmark where the 'low'
variable was counting in the wrong direction because it thought it could simply
add the result of the comparison.

[x86] Tweak the v16i8 single input special case lowering for shuffles

Previously, we would try much too hard to arrange a sequence of i8s in
one half of the input such that we could unpack them into i16s and
shuffle those into place. This isn't always going to be a cheaper i8
shuffle than our other strategies. The case where it is always going to
be cheaper is when we can arrange all the necessary inputs into one half

also makes it much easier to produce an efficient set of shuffles to
move the inputs into one half and then unpack them.

Recommit r212203: Don't try to construct debug LexicalScopes hierarchy for functions that do not have top level debug information.
Reverted by Eric Christopher (Thanks!) in r212203 after Bob Wilson
reported LTO issues. Duncan Exon Smith and Aditya Nandakumar helped
provide a reduced reproduction, though the failure wasn't too hard to
guess, and even easier with the example to confirm.
The assertion that the subprogram metadata associated with an
llvm::Function matches the scope data referenced by the DbgLocs on the
instructions in that function is not valid under LTO. In LTO, a C++
inline function might exist in multiple CUs and the subprogram metadata
nodes will refer to the same llvm::Function. In this case, depending on
the order of the CUs, the first intance of the subprogram metadata may
not be the one referenced by the instructions in that function and the
assertion will fail.
A test case (test/DebugInfo/cross-cu-linkonce-distinct.ll) is added, the
assertion removed and a comment added to explain this situation.
Original commit message:
If a function isn't actually in a CU's subprogram list in the debug info
metadata, ignore all the DebugLocs and don't try to build scopes, track
variables, etc.
While this is possibly a minor optimization, it's also a correctness fix
for an incoming patch that will add assertions to LexicalScopes and the
debug info verifier to ensure that all scope chains lead to debug info
for the current function.
Fix up a few test cases that had broken/incomplete debug info that could
violate this constraint.
Add a test case where this occurs by design (inlining a
debug-info-having function in an attribute nodebug function - we want
this to work because /if/ the nodebug function is then inlined into a
debug-info-having function, it should be fine (and will work fine - we
just stitch the scopes up as usual), but should the inlining not happen
we need to not assert fail either).

Dont' use a random probe & alloc strategy for the IRMemoryMap.
The current strategy for host allocation is to choose a random
address and attempt to allocate there, eventually failing if the
allocation cannot be satisfied.
The C standard only guarantees that RAND_MAX >= 32767, so for
platforms that use a very small RAND_MAX allocations will fail
with very high probability. On such platforms (Windows is one),
you can reproduce this trivially by running lldb, typing "expr (3)"
and then hitting enter you see a failure. Failures generally
happen with a frequency of about 1 failure every 5 evaluations.
There is no good reason that allocations need to look like "real"
pointers, so this patch changes the allocation scheme to simply
jump straight to the end and grab a free chunk of memory.

Fix tests broken by the OptionValidator changes.
The getopt library has a structure called option (lowercase). We
have a structure called Option (uppercase). previously the two
structures had exactly the same definitions, and we were doing a
C-style cast of an Option* to an option*. C-style casts don't
bother to warn you when you cast to unrelated types, but in the
original OptionValidator patch I modified the definition of Option.
This patch fixes the errors by building an array of option
structures and filling it out the correct way before passing it to
the getopt library.
This also fixes one other source of test failures: an uninitialized
read that occurs due to not initializing a field of the
OptionDefinition.
