[OpenMP] [OMPD] OPENMP_INSTALL_LIBDIR is set for the install dir

OPENMP_INSTALL_LIBDIR is set to the installation path of shared and static
libompd.This should avoid the mixing of 32 and 64 bit on same path in
multi-lib set-up.

[lldb] [testsuite] Fix false failures on "\n" regex match

Regex is matching a binary so it needs `re.DOTALL`.
vFile:fstat packet data ATTACHMENT is not hex-encoded but it is only
escaped.

It is difficult to reproduce, it came from buildbot:

Add sanity check in MLIR ODS to catch case where an arguments/results/regions/successors names overlap

This is making a tablegen crash with a more friendly error.

[mlir] Allows to query traits from types and attributes

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.

[JITLink] Add initial native TLS support to ELFNix platform

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.
