Enrico Granata d595733617 Fix a bug where trying to Dump() a ValueObject would use the static/non-synthetic version of the value even if the ValueObject one actually called Dump() on turned out to be dynamic and/or synthetic
This was of course overridable by using DumpValueObjectOptions, but the default should be saner and the previous behavior made for a few fun investigations....

Adhemerval Zanella 4bcc13d988 [ELF/AArch64] Fix correct TCB aligment calculation
This patch fixes the TLS local relocations alignment done by @238258.
As pointed out, the TLS size should not be considered, but rather the
TCB size based on maximum output segment alignment.  Although it has
not shown in the TLS simple cases for test-suite, more comprehensible
tests with more local TLS variable showed wrong relocations values
being generated.

The local TLS testcase is expanded to add more tls variable (both
exported and static) initialized or not.

Frederic Riss 90e0bd96ff Reapply r238941 - [dsymutil] Accept a YAML debug map as input instead of a binary.
With a couple more constructors that GCC thinks are necessary.

Original commit message:

[dsymutil] Accept a YAML debug map as input instead of a binary.

To do this, the user needs to pass the new -y flag.
As it wasn't tested before, the debug map YAML deserialization was
completely buggy (mainly because the DebugMapObject has a dual
mapping that allows to search by name and by address, but only the
StringMap got populated). It's fixed and tested in this commit by
augmenting some test with a 2 stage dwarf link: a frist llvm-dsymutil
reads the debug map and pipes it in a second instance that does the
actual link without touching the initial binary.

Tim Northover 5af339a1a9 RuntimeDyld: override EH frame registration with trivial version.
llvm-rtdyld was relying on the default memory manager's EH frame registration,
which is host-dependent rather than target-dependent. As a result, big-endian
ELF Mips EH frames were being registered on OS X (and elsewhere). This is a
really bad idea.

Frederic Riss 34238cfa24 [dsymutil] Replace -parse-only option with -dump-debug-map
As the serialized debug map is becoming a first class citizen, a way
to cleanly dump it is required. We used -parse-only combined with
-v for that purpose before, but it dumps a lot of unrelated debug
stuff. Dumping the debug map was the only use of the -parse-only flag
anyway, so replace it with a more useful option.

Matthias Braun 125c9f5f7b ARM: Thumb2 LDRD/STRD supports independent input/output regs
The existing code would unnecessarily break LDRD/STRD apart with
non-adjacent registers, on thumb2 this is not necessary.

Ideally on thumb2 we shouldn't match for ldrd/strd pre-regalloc anymore
as there is not reason to set register hints anymore, changing that is
something for a future patch however.

Tobias Grosser 224b162280 Only convert power-of-two floor-division with non-negative denominator
floord(a,b) === a ashr log_2 (b) holds for positive and negative a's, but
shifting only makes sense for positive values of b. The previous patch did
not consider this as isl currently always produces postive b's. To avoid future
surprises, we check that b is positive and only then apply the optimization.

We also now correctly check the return value of the dyn-cast.

No additional test case, as isl currently does not produce negative
denominators.

Daniel Sanders 8b2354de81 Re-commit r238838, r238844 with fix for host/target endian mismatch and windows buildbot.
The windows buildbot originally failed because the check expressions are
evaluated as 64-bit values, even for 32-bit symbols. Fixed this by comparing
bottom 32-bits of the expressions.

The host/target endian mismatch issue is that it's invalid to read/write target
values using a host pointer without taking care of endian differences between
the target and host. Most (if not all) instances of
reinterpret_cast<uint32_t*>() in the RuntimeDyld are examples of this bug.
This has been fixed for Mips using the endian aware read/write functions.
