69fadae872 Really fix the build this time.
I was setting the python variable to "@HAVE_DIA_SDK@", which will
always be a string, and will always evaluate to True.

ca27e720c3 Attempt to fix the builders.
The issue was that the test Makefile had not been updated to
provide a value for HAVE_DIA_SDK, so it was being initialized
incorrectly.  Hopefully this brings everything back to green.

eec34e5ed4 [llvm-pdbdump] Resubmit "Add some tests for llvm-pdbdump".
NOTE: This patch intentionally breaks the build.  It attempts
to resubmit r230083, but with some debug logging in the CMake
and lit config files to determine why certain bots do not
correctly disable the DIA tests when DIA is not available.

After a sufficient number of bots fail, this patch will either
be reverted or, if the cause of the failure becomes obvious,
a fix submitted with the log statements removed.

b9b88bd77b IRCE: generalize InductiveRangeCheck::computeSafeIterationSpace to
work with a non-canonical induction variable.

This is currently a non-functional change because we only ever call
computeSafeIterationSpace on a canonical induction variable; but the
generalization will be useful in a later commit.

ca7e0787f0 CodeGen: convert CCState interface to using ArrayRefs
Everyone except R600 was manually passing the length of a static array
at each callsite, calculated in a variety of interesting ways. Far
easier to let ArrayRef handle that.

There should be no functional change, but out of tree targets may have
to tweak their calls as with these examples.

9f8d4037a6 AsmParser/Writer: Handle symbolic constants in DI 'flags:'
Parse (and write) symbolic constants in debug info `flags:` fields.
This prevents a readability (and CHECK-ability) regression with the new
debug info hierarchy.

Old (well, current) assembly, with pretty-printing:

    !{!"...\\0016387", ...} ; ... [public] [rvalue reference]

Flags field without this change:

   !MDDerivedType(flags: 16387, ...)

Flags field with this change:

   !MDDerivedType(flags: DIFlagPublic | DIFlagRValueReference, ...)

As discussed in the review thread, this isn't a final state.  Most of
these flags correspond to `DW_AT_` symbolic constants, and we might
eventually want to support arbitrary attributes in some form.  However,
as it stands now, some of the flags correspond to other concepts (like
`FlagStaticMember`); until things are refactored this is the simplest
way to move forward without regressing assembly.

7a62a2a5ae [PlaceSafepoints] Adjust enablement logic to default to off and be GC configurable per GC
Previously, this pass ran over every function in the Module if added to the pass order.  With this change, it runs only over those with a GC attribute where the GC explicitly opts in.  A GC can also choose which of entry safepoint polls, backedge safepoint polls, and call safepoints it wants.  I hope to get these exposed as checks on the GCStrategy at some point, but for now, the checks are manual string comparisons.

efcb266311 AsmParser: Use do{}while(false) in macros, NFC
`do { ... } while (false)` is standard macro etiquette for forcing
instantiations into a single statement and requiring a `;` afterwards,
making statement-like macros easier to reason about (and harder to use
incorrectly).

I'm about to modify the macros in `LexIdentifier()`.  I noticed that the
`KEYWORD` macro *does* follow the rule, so I thought I'd clean up the
other macros to match (otherwise might not be worth changing, since the
benefits of this pattern are fairly irrelevant here).

b2c6bf6776 LiveRangeCalc: Don't start liveranges of PHI instruction at the block begin.
Summary:
Letting them begin at the PHI instruction slightly simplifies the code
but more importantly avoids breaking the assumption that live ranges
starting at the block begin are also live at the end of the predecessor
blocks. The MachineVerifier checks that but was apparently never run in
the few instances where liveranges are calculated for machine-SSA
functions.
