For now most are implemented by printing out the name of the filesystem,
but this can be expanded in the future. Only `OverlayFileSystem` and
`RedirectingFileSystem` are properly implemented in this patch.
- `OverlayFileSystem`: Prints each filesystem in the order that any
operations are actually run on them. Optionally prints recursively.
- `RedirectingFileSystem`: Prints out all mappings, as well as the
`ExternalFS`. Most of this was already implemented other than the
handling for the `DirectoryRemap` case and to actually print out the
mapping.
Each FS should implement `printImpl` rather than `print`, where the
latter just fowards to the former. This is to avoid spreading the
default arguments through to the subclasses (where we may miss updating
in the future).

This patch refactors the current coalesce implementation. It introduces
the `SetCoalescer`, a class in which all coalescing functionality lives.
The main advantage over the old design is the fact that the vectors of
constraints do not have to be passed around, but are implemented as
private fields of the SetCoalescer. This will become especially
important once more inequality types are introduced.

D120762 accidentally moved the interrupt check into the block which was
reading stdio. This meant that a ^C only took effect after a regular
character has been pressed.
This patch fixes that and adds a (pexpect) test.

FLT_EVAL_METHOD tells the user the precision at which, temporary results
are evaluated but when fast-math is enabled, the numeric values are not
guaranteed to match the source semantics, so the eval-method is
meaningless.
For example, the expression `x + y + z` has as source semantics `(x + y)
+ z`. FLT_EVAL_METHOD is telling the user at which precision `(x + y)`
is evaluated. With fast-math enable the compiler can choose to
evaluate the expression as `(y + z) + x`.
The correct behavior is to set the FLT_EVAL_METHOD to `-1` to tell the
user that the precision of the intermediate values is unknow. This
patch is doing that.

We've been meaning to remove support for the legacy testing configuration
for a long time. This patch switches the default from the legacy config
to the appropriate new-style configuration based on a few hints.
We've been running with the new-style configuration for more than a year
in our CI, however it's possible that this will uncover issues with some
users that run the tests on platforms that we don't support yet with the
new-style configs. Unfortunately, there is no way to know about it other
than to land this patch and see whether anything breaks.

No need to schedule entry nodes where all instructions are not memory
read/write instructions and their operands are either constants, or
arguments, or phis, or instructions from others blocks, or their users
are phis or from the other blocks.
The resulting vector instructions can be placed at
the beginning of the basic block without scheduling (if operands does
not need to be scheduled) or at the end of the block (if users are
outside of the block).
It may save some compile time and scheduling resources.

For MachO, lower `@llvm.global_dtors` into `@llvm_global_ctors` with
`__cxa_atexit` calls to avoid emitting the deprecated `__mod_term_func`.
Reuse the existing `WebAssemblyLowerGlobalDtors.cpp` to accomplish this.
Enable fallback to the old behavior via Clang driver flag
(`-fregister-global-dtors-with-atexit`) or llc / code generation flag
(`-lower-global-dtors-via-cxa-atexit`). This escape hatch will be
removed in the future.

When the sparse_tensor dialect lowers linalg.generic,
it makes inferences about how the operations should
affect the looping logic. For example, multiplication
is an intersection while addition is a union of two
sparse tensors.
The new binary and unary op separate the looping logic
from the computation by nesting the computation code
inside a block which is merged at the appropriate level
in the lowered looping code.
The binary op can have custom computation code for the
overlap, left, and right sparse overlap regions. The
unary op can have custom computation code for the
present and absent values.

There is a crash in the ARM backend when attempting to decode a "tsb
csync" instruction using `llvm-objdump --triple=armv8.4a -d`. The crash
was in `ARMMCInstrAnalysis::evaluateBranch` where the number of operands
in the decoded instruction (0) did not match the number of operands in
the instruction description (1).
This is becuase `tsb csync` looks like it has an operand during
assembly, but there is only one valid operand (csync), so there is no
encoding space in the instruction for the operand, so the decoder never
has a field to decode that represents `csync`.
The fix is to add a custom decode method, which ensures that this
instruction does have the right number of operands after decoding. This
method merely adds the only available operand value, `ARM_TSB::CSYNC`.

The strippable Swift reflection sections contain subtractor relocations
that need to be applied. There are two situations we need to support.
1) Both symbols used in the relocation come from the .o file (for
example, one symbol lives in __swift5_fieldmd and the second in
__swift5_reflstr).
2) One symbol comes from th .o file and the second from the main
binary (for example, __swift5_fieldmd and __swift5_typeref).

Tests can register multiple allocators, but only the first will initialize since it initializes the TSDRegistrySharedT. Then, destruction of subsequent allocator may end up unmapping a nullptr PrimaryBase with non-zero PrimarySize.

When we build clang without asserts we should still check the result of
`InlineFunction()` to be sure there wasn't an error. Otherwise we could
incorrectly merge attributes in the next line.
This also removes a redundent call to `getCaller()`.

This reverts commit c46aab01c0.
This evidently blocks compiling in some cases that used to work
before. I'm also not fully convinced this is the correct place to fix
this problem.
Currently we allow half types in vectors if the scalar Zfh extension
is enabled. This behavior is not inline with the vector spec. For f32
and f64 types, the Zve32f, Zve64f, Zve64d, and V explicitly control
the availablity of floating point types in vectors.
In order to make our compiler compliant, we either need to remove all support
for half in vectors or we need an extension to control it.

All option forwarding tests should be added to frontend-forwarding.f90
rather than files corresponding to various options. This patch moves
such test for `-mllvm` accordingly.
Since we have SPLAT_VECTOR_PARTS these days, I don't think we need
to go through extra lengths to avoid introducing an illegal scalar type.
We can just call getConstant using the scalable vector type and let
it create either a SPLAT_VECTOR or a SPLAT_VECTOR_PARTS.
