This reverts commit 79caedf5.

This patch splits the GlobalISelEmitter.cpp file, which imports DAG ISel patterns for GISel, into separate "GISelMatchTable.h/cpp" files.

The main motive is readability & maintainability. GlobalISelEmitter.cpp was about 6400 lines of mixed code, some bits implementing the match table codegen, some others dedicated to importing DAG patterns.

Now it's down to  2700 + a 2150 header + 2000 impl.
It's a tiny bit more lines overall but that's to be expected - moving
inline definitions to out-of-line, adding comments in the .cpp, etc. all of that takes additional space, but I think the tradeoff is worth it.

I did as little unrelated code changes as possible, I would say the biggest change is the introduction of the `gi` namespace used to prevent name conflicts/ODR violations with type common names such as `Matcher`.
It was previously not an issue because all of the code was in an anonymous namespace.

This moves all of the "match table" code out of the file, so predicates,
rules, and actions are all separated now. I believe this helps separating concerns, now `GlobalISelEmitter.cpp` is more focused on importing DAG patterns into GI, instead of also containing the whole match table internals as well.

Note: the new files have a "GISel" prefix to make them distinct from the other "GI" files in the same folder, which are for the combiner.

This reverts commit 4054c686.

Due to AIX system linker requires DWARF64 for XCOFF64.

Differential Revision: https://reviews.llvm.org/D151998

The change implements intrinsics 'get_fpenv', 'set_fpenv' and 'reset_fpenv'.
They are used to read floating-point environment, set it or reset to
some default state. They do the same actions as C library functions
'fegetenv' and 'fesetenv'. By default these intrinsics are lowered to calls
to these functions.

The new intrinsics specify FP environment as a value of integer type, it
is convenient of most targets where the FP state is a content of some
register. Some targets however use long representations. On X86 the size
of FP environment is 256 bits, and even half of this size is not a legal
ibteger type. To facilitate legalization in such cases, two sets of DAG
nodes is used. Nodes GET_FPENV and SET_FPENV are used when FP
environment may be represented by a legal integer type. Nodes
GET_FPENV_MEM and SET_FPENV_MEM consider FP environment as a region in
memory, much like `fesetenv` and `fegetenv` do. They are used when
target has long representation for floationg-point state.

Correctly account for the fact that certain targets do not use the generic address space for the implicit VTT argument. This entails adjusting `ItaniumCXXABI::buildStructorSignature`, `ItaniumCXXABI::addImplicitStructorParams` and `ItaniumCXXABI::getImplicitConstructorArgs` to use the target's global variable address space. The associated test is temporarily marked `XFAIL` as additional fixes are needed.

Enables reserving or marking dead in enum list, resulting in skipping in dispatches.

Fix missed review comment from https://reviews.llvm.org/D144820

The comment moved is referring to the --output-asm-syntax flag rather
than the --print-imm-hex flag, but seems to have mistakenly been put
under the definition of that flag due to some misplaced line numbers on
phabricator.

If the value was already known to not be uniform for the previous
(smaller VF), it cannot be uniform for the larger VF.

This slightly reduces compile-time, once uniformity checks are becoming
a bit more expensive due to using SCEV rewriting (D148841).
