Chunk has writeTo function which takes uint8_t *Buf.
writeHeaderTo feels more consistent with that because this member
function also takes uint8_t *Buf.

Previously, half of the constructor for .idata contents was in Chunks.cpp
and the rest was in Writer.cpp. This patch moves the latter to Chunks.cpp.
Now IdataContents class manages everything for .idata section.

There were several SelectInst combines that always returned an existing
instruction instead of modifying an old one or creating a new one.
These are prime candidates for moving to InstSimplify.

Summary:
canUnrollCompletely takes `unsigned` values for `UnrolledCost` and
`RolledDynamicCost` but is passed in `uint64_t`s that are silently
truncated. Because of this, when `UnrolledSize` is a large integer
that has a small remainder with UINT32_MAX, LLVM tries to completely
unroll loops with high trip counts.

CVP wants to analyze the condition operand of a select along an edge.
It succeeds in getting back a Constant but not a ConstantInt. Instead,
it gets a ConstantExpr. It then assumes that the Constant must be equal
to false because it isn't equal to true.
Instead, perform an additional comparison.
This fixes PR23752.

In this design, Chunk is the only thing that knows how to write
its contents to output file as well as how to apply relocations
there. The writer shouldn't know about the details.

If we have (select a, b, c), it is sometimes valid to simplify this to a
single select operand. However, doing so is only valid if the
computation doesn't inject poison into the computation.
It might be helpful to consider the following example:
(select (icmp ne %i, INT_MAX), (add nsw %i, 1), INT_MIN)
The select is equivalent to (add %i, 1) but not (add nsw %i, 1).
Self hosting on x86_64 revealed that this occurs very, very rarely so
bailing out is hopefully pretty reasonable.

LLDB included editline in a couple of places, not respecting LLDB_DISABLE_LIBEDIT. As far as I can tell, these includes are not used, so I am removing them.

Linking the debug frame section is actually very easy as we just have to
patch the start address in the FDE header and then copy the rest of the
FDE without even looking at it. The only small complexity comes from the
handling of the CIEs that we should unique across object file. This is
also really easy by using a StringMap keyed on the raw contents of the
CIE.

It's better not to rely on the diagnostics engine to pretty print the
argument to decltype. Instead, exercise the functionality in
DeclPrinterTest.

Summary:
Update DYLDRendezvous and SOEntry to use FileSpecs instead of storing paths as
strings, which caused incorrect comparison results due to denormalization.

the overloaded version of addPass which takes Pass*.
This change enables inserting the machine printer pass when the overloaded
version of addPass that takes Pass* is called to add a pass, instead of the
one which takes AnalysisID. I need this to prevent make-check tests from
failing when I commit another patch later.

The main use of the YAML debug map format is for testing inside LLVM. If we have IR
files in the tests used to generate object files, then we obviously don't know the
addresses of the symbols inside the object files beforehand.
This change lets the YAML import lookup the addresses in the object files and rewrite
them. This will allow to have test that really don't need any binary input.
