[XRay][compiler-rt] Support string-based config for Basic mode.

Summary:
This addresses http://llvm.org/PR36790.

This change allows the XRay Basic Mode implementation to use the
string-based initialization routine provided through
`__xray_log_init_mode(...)`. In the process, we've also deprecated some
flags defined for the `XRAY_OPTIONS` environment variable.

We then introduce another environment variable that can control the XRay
Basic Mode implementation through `XRAY_BASIC_OPTIONS`.

We also rename files from `xray_inmemory_log` to `xray_basic_logging` to
be more in line with the mode implementation.

Depends on D46174.

functionality.

- `__xray::FDRLoggingOptions` -- in following patches, we'll be

The on-ios-device command line lldb has an optimization where
when it and the inferior process both have the same shared cache
(a conglomeration of all libraries at the same fixed address for
all processes), lldb will read data out of its own memory to speed
things up.  The shared cache has a UUID, so lldb currently checks
that the UUID of its own shared cache matches that of the inferior.

This change adds one refinement to that -- it checks that the UUID
is the same and that the base address of the shared cache is the
same.  And only uses its local shared cache if they are both identical.

This involved using a different style of SPI with dyld to get lldb's
shared cache load address, but it's not especially difficult.

One unattractive part of the change is that I'm using the real
underlying types of task_t and kern_return_t instead of picking
them up from mach/mach.h.  The defines that get picked up there (a

int cnt = 0;
while (x) {
  x >>= 1; // arithmetic shift right

}

and turn it into (bitwidth - ctlz(x)). And if there is anything else in the loop we will create a new loop that runs that many times.

If x is initially negative, the shift result will never be 0 and thus the loop is infinite. If you put something with side effects in the loop, that side effect will now only happen bitwidth times instead of an infinite number of times.

reduced to just a bitwise logic instruction, and remove an
over-reaching chunk of general purpose bit magic. The primary goal
is to remove cases where we are not improving the IR instruction
count when doing these select transforms, and in all cases here that
is true.

In the motivating 3-way compare tests, there are further improvements
because we can combine/propagate select values (not sure if that
belongs in instcombine, but it's there for now).

DAGCombiner has folds to turn some of these selects into bit magic,
so there should be no difference in the end result in those cases.
Not all constant combinations are handled there yet, however, so it
is possible that some targets will see more cmov/csel codegen with
this change in IR canonicalization.

Ideally, we'll go further to *not* turn selects into multiple
logic/math ops in instcombine, and we'll canonicalize to selects.
But we should make sure that this step does not result in regressions
first (and if it does, we should fix those in the backend).

[DebugInfo] Correction for an assert in DIExpression::createFragmentExpression

Summary:
When we create a fragment expression, and there already is an
old fragment expression, we assert that the new fragment is
within the range for the old fragment.

If for example the old fragment expression says that we
describe bit 10-16 of a variable (Offset=10, Size=6),
and we now want to create a new fragment expression only
describing bit 3-6 of the original value, then the resulting
fragment expression should have Offset=13, Size=3.

The assert is supposed to catch if the resulting fragment
expression is outside the range for the old fragment. However,
it used to verify that the Offset+Size of the new fragment was
smaller or equal than Offset+Size for the old fragment. What
we really want to check is that Offset+Size of the new fragment
is smaller than the Size of the old fragment.

Reapply "[SelectionDAG] Selection of DBG_VALUE using a PHI node result (pt 2)"

Summary:
This reverts SVN r331441 (reapplies r331337), together with a fix
in to handle an already existing fragment expression in the
dbg.value that must be fragmented due to a split PHI node.

This should solve the problem seen in PR37321, which was the
reason for the revert of r331337.

The situation in PR37321 is that we have a PHI node like this

   %u.sroa = phi i80 [ %u.sroa.x, %if.x ],
                     [ %u.sroa.y, %if.y ],
                     [ %u.sroa.z, %if.z ]

and a dbg.value like this

  call void @llvm.dbg.value(metadata i80 %u.sroa,
                            metadata !13,
                            metadata !DIExpression(DW_OP_LLVM_fragment, 0, 80))

The phi node is split into three 32-bit PHI nodes

  %30:gr32 = PHI %11:gr32, %bb.4, %14:gr32, %bb.5, %27:gr32, %bb.8
  %31:gr32 = PHI %12:gr32, %bb.4, %15:gr32, %bb.5, %28:gr32, %bb.8
  %32:gr32 = PHI %13:gr32, %bb.4, %16:gr32, %bb.5, %29:gr32, %bb.8

but since the original value only is 80 bits we need to adjust the size
of the last fragment expression, and with this patch we get

  DBG_VALUE debug-use %30:gr32, debug-use $noreg, !"u", !DIExpression(DW_OP_LLVM_fragment, 0, 32)
  DBG_VALUE debug-use %31:gr32, debug-use $noreg, !"u", !DIExpression(DW_OP_LLVM_fragment, 32, 32)

[CMake] Unify and relayer testing

This patch restructures part of LLDB's testing configuration:

1. I moved the test dependencies up the chain so every dotest dependency
   becomes a lit dependency as well. It wouldn't make sense for dotest to
   have other dependencies when it's being run by lit. Lit on the other
   hand can still specify extra dependencies.

2. I replaced as much generator expressions with variables as possible.
   This is consistent with the rest of LLVM and doesn't break generators
   that support multiple targets (MSVC, Xcode). This wasn't a problem
   before, but now we need to expand the dotest arguments in the lit
   configuration and there's only one test suite even with multiple
   targets.

3. I moved lldb-dotest into it's own directory under utils since there's
   no need anymore for it to located under `test/`.

DWARFExpression: Convert file addresses to load addresses early on.

This is a change that only affects Swift and is NFC for the language
plugins on llvm.org. In Swift, we can have global variables with a
location such as DW_OP_addr <addr> DW_OP_deref. The DWARF expression
evaluator doesn't know how to apply a DW_OP_deref to a file address,
but at the very end we convert the file address into a load address.

This patch moves the file->load address conversion to right after the
result of the DW_OP_addr is pushed onto the stack so that a subsequent
DW_OP_deref (and potentially other operations) can be interpreted.
