[MC, COFF] Unbreak support for COFF timestamps

Support for COFF timestamps was unintentionally broken in r246905 when
it was conditionally available depending on whether or not LLVM was
configured with LLVM_ENABLE_TIMESTAMPS.  However, Config/config.h was
never included which essentially broke the feature.  Due to lax testing,
the breakage was never identified until we observed strange failures
during incremental links of Chromium.

This issue is resolved by simply including Config/config.h in
WinCOFFObjectWriter and teaching lit that the MC/COFF/timestamp.s test
is conditionally supported depending on LLVM_ENABLE_TIMESTAMPS.  With
this in place, we can strengthen the test to ensure that it will not
accidentally get broken in the future.

[PGO] Improve Indexed Profile Reader efficiency

With the support of value profiling added, the Indexed prof
reader gets less efficient. The prof reader initialization
used to be just reading the file header, but with VP support
added, initialization needs to walk through all profile keys
of ondisk hash table resulting in very poor locality and large
memory increase (keys are stored together with the profile data
in the mapped profile buffer). Even worse, when the reader is
used by the compiler (not llvm-profdata too), the penalty becomes
very high as compilation of each single module requires touching
profile data buffer for the whole program.

In this patch, the icall target values (MD5hash) are no longer eargerly
converted back to name strings when the data is read into memory. New
interface is added to to profile reader so that InstrProfSymtab can be
lazily created for Indexed profile reader on-demand. Creating of the

of  VP data. It can be used with compiler (for legacy out of tree uses)
too but not recommended due to compile time and memory reasons

Clean up the processing of dbg.value in various places

First up is instcombine, where in the dbg.declare -> dbg.value conversion,
the llvm.dbg.value needs to be called on the actual loaded value, rather
than the address (since the whole point of this transformation is to be
able to get rid of the alloca). Further, now that that's cleaned up, we
can remove a hack in the backend, that would add an implicit OP_deref if
the argument to dbg.value was an alloca. This stems from before the
existence of DIExpression and is no longer necessary since the deref can
be expressed explicitly.

Now, in order to make sure that the tests pass with this change, we need to
correct the printing of DEBUG_VALUE comments to take into account the
expression, which wasn't taken into account before.

Unfortunately, for both these changes, there were a number of incorrect
test cases (mostly the wrong number of DW_OP_derefs, but also a couple
where the test itself was broken more badly). aprantl and I have gone
through and adjusted these test case in order to make them pass with
these fixes and in some cases to make sure they're actually testing
what they are meant to test.

Do the simplest possible thing that guarantees the correct order of moves

last part forces some trivial adjustments to test cases.)

While at it, change the generation of kill and def flags to something that
looks more reasonable. This method is used very late during compilation, so
it probably doesn't matter in practice, and to be honest, I don't know if
this change is actually correct because the semantics in connection with
aggregate registers vs. sub-registers are not clear to me.

LLVM MC has single methods which can handle the output of EH frame and DWARF CIE's and FDE's.

This code improves DWARFDebugFrame::parse to do the same for parsing.

option dumps the .eh_frame section using the new code in DWARFDebugFrame::parse.
