Test cases may want to use the host compiler to compile some mocks for the
test case.
This patch adds two substitutions `%host_cc` and `%host_cxx` to use the host
compilers set via variable `CMAKE_C_COMPILER` and `CMAKE_CXX_COMPILER`.

When building in MSVC mode (in release mode), the assert(false) don't
make the end of the function unreachable, so add return statements to
silence compiler warnings (treated as errors).
Also change 'virtual' into 'override', which was requested in review,

This commit adds a full WasmTableType to MCSymbolWasm, differing from
the current situation (just an ElemType) in that it additionally records
a WasmLimits.
We add support for specifying the limits in .S files also, via the
following syntax variations:
.tabletype SYM, ELEMTYPE
.tabletype SYM, ELEMTYPE, MINSIZE
.tabletype SYM, ELEMTYPE, MINSIZE, MAXSIZE
Depends on D99186.

This mechanism makes it possible for a dialect to not register all
operations but still answer interface-based queries.
This can useful for dialects that are "open" or connected to an external
system and still interoperate with the compiler. It can also open up the
possibility to have a more extensible compiler at runtime: the compiler
does not need a pre-registration for each operation and the dialect can
inject behavior dynamically.

This patch renames the "Initial" member of WasmLimits to the name used
in the spec, "Minimum".
In the core WebAssembly specification, the Limits data type has one
required "min" member and one optional "max" member, indicating the
minimum required size of the corresponding table or memory, and the
maximum size, if any.
Although the WebAssembly spec does instantiate locally-defined tables
and memories with the initial size being equal to the minimum size, it
can't impose such a requirement for imports. It doesn't make sense to
require an initial size for a memory import, for example. The compiler
can only sensibly express the minimum and maximum sizes.
See
https://github.com/WebAssembly/js-types/blob/master/proposals/js-types/Overview.md#naming-of-size-limits
for a related discussion that agrees that the right name of "initial" is
"minimum" when querying the type of a table or memory from JavaScript.
(Of course it still makes sense for JS to speak in terms of an initial
size when it explicitly instantiates memories and tables.)

There are a number of functions in altivec.h that use
vector __int128 which isn't supported on AIX. Those functions
need to be guarded for targets that don't support the type.
Furthermore, the functions that produce quadword instructions
without using the type need a builtin. This patch adds the
macro guards to altivec.h using the __SIZEOF_INT128__ which
is only defined on targets that support the __int128 type.
The original comment says the same thing twice, and does not mention that
edges entering the block are also in the same bundle (which seems true from
what the underlying code is doing).

Statepoint instruction is known to have a variable and big number of operands.
It is possible that Register Allocator will split live intervals in the way that all
physical registers are occupied by "zero-length" live intervals which are marked
as not-spillable.
While intervals are marked as not-spillable in the moment of creation when they are
really zero-length it is possible that in future as part of re-materialization there will
need for physical register between def and use of such tiny interval (the use is not
related to this interval at all).
As all physical registers are assigned to not-spillable intervals there is not avaialbe
registers and RA reports an error.
The idea of the fix is avoid marking tiny live intervals where there is a use in statepoint
instruction in var args section. Such interval may be perfectly spilled and folded to
operand of statepoint.

None of the code in this function was written to handle
vectors. Most of the cases already fail for vectors for one
reason or another. The exception is an optimization that
detects identical operands. This can be triggered by vectors,
but the code always creates a 0 or 1 constants in a scalar
register which is incorrect for vectors.
Fixes PR49706.

The current implementation keeps buffers generated for each object file
until it completes loading of all files. This approach requires a lot of memory
if there are a lot of huge object files. Thus, make it to load coverage records
immediately rather than waiting for other binaries to be loaded.
This reduces memory usage of llvm-cov from >128GB to 5GB when
loading Chromium binaries in Windows.

To match an interface or trait, users currently have to use the `MatchAny` tag. This tag can be quite problematic for compile time for things like the canonicalizer, as the `MatchAny` patterns may get applied to *every* operation. This revision adds better support by bucketing interface/trait patterns based on which registered operations have them registered. This means that moving forward we will only attempt to match these patterns to operations that have this interface registered. Two simplify defining patterns that match traits and interfaces, two new utility classes have been added: OpTraitRewritePattern and OpInterfaceRewritePattern.
