The patch adds missing diagnostics for cases like:
float F3 = ((__float128)F1 * (__float128)F2) / 2.0f;
Sema::checkDeviceDecl (renamed to checkTypeSupport) is changed to work
with a type without the corresponding ValueDecl. It is also refactored
so that host diagnostics for unsupported types can be added here as
well.

This patch fixes initializing temporaries, which are currently initialized
without an address space, meaning that no constructor can ever be applicable.
Now they will be constructed in the private addrspace.
Fixes the second issue in PR43296.

Previously, we would insert a DimOp and rely on later canonicalizations.
Unfortunately, reifyShape kind of rewrites are not canonicalizations anymore.
This introduces undesirable pass dependencies.
Instead, immediately reify the result shape and avoid the DimOp altogether.
This is akin to a local folding, which avoids introducing more reliance on `-resolve-shaped-type-result-dims` (similar to compositions of `affine.apply` by construction to avoid chains of size > 1).
It does not completely get rid of the reliance on the pass as the process is merely local: calling the pass may still be necessary for global effects. Indeed, one of the tests still requires the pass.

Remove redundant register alt_names that correspond to their respective
generic names. D108554 makes it possible to query registers through
their generic names directly, therefore making repeating them via
alt_name unnecessary.
While at it, also remove alt_names that are equal to register names
on PPC.
This patch does not alter register definitions where the generic names
are listed as primary names, and other names are provided as alt_name
(e.g. ARM).

Update GetRegisterInfoByName() methods to support getting registers
by a generic name independently of alt_name entries in the register
context. This makes it possible to use generic names when interacting
with gdbserver (that does not supply alt_names). It also makes it
possible to remove some of the duplicated information from register
context declarations and/or use alt_names for another purpose.

For certain patterns that restrict the range of an index, we can insert

This extends the custom lowering for extending loads on
fixed length vectors in SVE to support masked extending loads.
The existing tests for correct behaviour of masked extending loads
exhibit bad code generation due to the legalistaion of i1 vectors.
They have been left as-is and new tests have been added that do not
exhibit this behaviour.

The packed variants of the instructions had been modelled as the same as the scalar variants.
Reported during a run of llvm-exegesis on a cheap SLM box and matches what Agner / InstLatX64 report as well.
This patch use the same way as the https://reviews.llvm.org/rGfe1fa43f16beac1506a2e73a9f7b3c81179744eb to handle the thread local variable.
It allocates 2 * pointerSize space in GOT to represent the thread key and data address. Instead of using the _tls_get_addr function, I customed a function __orc_rt_elfnix_tls_get_addr to get the address of thread local varible. Currently, this is a wip patch, only one TLS relocation R_X86_64_TLSGD is supported and I need to add the corresponding test cases.
To allocate the TLS descriptor in GOT, I need to get the edge kind information in PerGraphGOTAndPLTStubBuilder, So I add a `Edge::Kind K` argument in some functions in PerGraphGOTAndPLTStubBuilder.h. If it is not suitable, I can think further to solve this problem.

Types and attributes now have a `hasTrait` function that allow users to check
if a type defines a trait.
Also, AbstractType and AbstractAttribute has now a `hasTraitFn` field to carry
the implementation of the `hasTrait` function of the concrete type or attribute.
This patch also adds the remaining functions to access type and attribute traits
in TableGen.

This patch fixes a error made in 2cc6f7c8e1. That patch

the presence of a unknown call edge was being propagated from call site
to function. This patch fixes that error. This error was effecting some
AMDGPU tests.
This allows for a custom encoding to be emitted. It can also be
used with inline assembly to allow the custom instruction to be
register allocated like other instructions.
I initially started from SystemZ's implementation, but some of
the formats allow operands to be specified in multiple ways so I
had to add support for matching different operand class lists for
the same format. That implementation is a simplified version of
what is emitted by tablegen for regular instructions.
I've left out the compressed formats. And I haven't supported the
named opcodes like LUI or OP_IMM_32. Those can be added in future
patches.
