These are useful helpers over the low-level API of the FormattersContainer, and since we're actually going to start moving formatters into plugins, it makes sense to simplify things

the main attribute and cache the results so we don't have to parse
a single attribute more than once.
This reapplies r246596 with a fix for an uninitialized class member,
and a couple of cleanups and formatting changes.

Summary:
When calling find_first_of and find_last_of on a single character,
we can instead just call find / rfind and make our intent more
clear.

Summary:
This was removed from the other ABI plugins long ago. This removes
a warning that was happening in this unused code as a result of
adding 2 new types to Scalar.h (e_uint128 and e_sint128).

The MS incremental linker seems to inspect the timestamp written into
the object file to determine whether or not it's contents need to be
considered. Failing to set the timestamp to a date newer than the
executable will result in the object file not participating in
subsequent links. To ameliorate this, write the current time into the
object file's TimeDateStamp field.

Summary:
Comparing m_page_size against kInvalidPageSize was resulting in
a warning about comparing integers with different signs. Since
kInvalidPageSize isn't used anywhere outside of MachVMMemory.cpp,
we can readily transform it into a static const vm_size_t with
the correct value to avoid the sign comparison warnings.

The ELF spec says:
... if any reference to or definition of a name is a symbol with a
non-default visibility attribute, the visibility attribute must be
propagated to the resolving symbol in the linked object. If different
visibility attributes are specified for distinct references to or
definitions of a symbol, the most constraining visibility attribute
must be propagated to the resolving symbol in the linked object. The
attributes, ordered from least to most constraining, are:
STV_PROTECTED, STV_HIDDEN and STV_INTERNAL.

Summary:
`OpaqueValueExpr`s may not have a source expression (as in the case when
they are created due to a default argument error).
This can cause an assertion failure in `TransformOpaqueValueExpr` during
template instantiation.
This patch fixes the assertion failure.

The code introduced in r244314 assumed that EXTRACT_VECTOR_ELT only
takes constant indices, but it does accept variables.
Bail out for those: we can't use them, as the shuffles we want to
reconstruct do require constant masks.

COFF sections are accompanied with an auxiliary symbol which includes a
checksum. This checksum used to be filled with just zero but this seems
to upset LINK.exe when it is processing a /INCREMENTAL link job.
Instead, fill the CheckSum field with the JamCRC of the section
contents. This matches MSVC's behavior.
This fixes PR19666.
N.B. A rather simple implementation of JamCRC is given. It implements
a byte-wise calculation using the method given by Sarwate. There are
implementations with higher throughput like slice-by-eight and making
use of PCLMULQDQ. We can switch to one of those techniques if it turns
out to be a significant use of time.

r246546, with a workaround for an MSVC 2013 miscompile and an MSVC 2015
rejects-valid.
Original commit message:
[modules] Rework serialized DeclContext lookup table management. Instead of
walking the loaded ModuleFiles looking for lookup tables for the context, store
them all in one place, and merge them together if we find we have too many
(currently, more than 4). If we do merge, include the merged form in our
serialized lookup table, so that downstream readers never need to look at our
imports' tables.
This gives a huge performance improvement to builds with very large numbers of
modules (in some cases, more than a 2x speedup was observed).

This was last used by the pre-MC object emitter and has been dead for

Historically, data formatters all exist in a global repository (the category map)
On top of that, some formatters can be "hardcoded" when the conditions under which they apply are not expressible as a typename (or typename regex)
This change paves the way to move formatters into per-language buckets such that the C++ plugin is responsible for ownership of the C++ formatters, and so on
The advantages of this are:
a) language formatters only get created when they might apply
b) formatters for a language are clearly owned by the matching language plugin
The current model is one of static instantiation, that is a language knows the full set of formatters it vends and that is only asked-for once, and then handed off to the FormatManager
In a future revision it might be interesting to add similar ability to the language runtimes, and monitor for certain shared library events to add even more library-specific formatters
No formatters are moved as part of this change, so practically speaking this is NFC

By just removing dimensions (and the constraints they are involved in) we
may loose information about the dimensions we do not remove. By instead
using project_out, we are sure all constraints on the outer dimensions are
preserved.
No test case, as this error condition is very unlikely to be triggered by
isl's current code. We still 'fix' this, as isl gives little guarantees
regarding the behavior of remove_divs.
