[ARM] Rewrite isLegalT2AddressImmediate

This does two main things, firstly adding some at least basic addressing modes
for i64 types, and secondly treats floats and doubles sensibly when there is no
fpu. The floating point change can help codesize in some cases, especially with
D60294.

Most backends seems to not consider the exact VT in isLegalAddressingMode,
instead switching on type size. That is now what this does when the target does
not have an fpu (as the float data will be loaded using LDR's). i64's currently
use the address range of an LDRD (even though they may be legalised and loaded
with an LDR). This is at least better than marking them all as illegal
addressing modes.

I have not attempted to do much with vectors yet. That will need changing once
MVE is added.

[gn] Move Features.inc to clangd, create a config for it

ClangdLSPServer and clangd unittests now include Features.inc so we
need to append the target_gen_dir that contains it to their
include_dirs. To do so, we use a public config that's applied to
any target that depends on the features one.

Initial implementation of JITLink - A replacement for RuntimeDyld.

Summary:

JITLink is a jit-linker that performs the same high-level task as RuntimeDyld:
it parses relocatable object files and makes their contents runnable in a target
process.

JITLink aims to improve on RuntimeDyld in several ways:

(1) A clear design intended to maximize code-sharing while minimizing coupling.

RuntimeDyld has been developed in an ad-hoc fashion for a number of years and
this had led to intermingling of code for multiple architectures (e.g. in
RuntimeDyldELF::processRelocationRef) in a way that makes the code more
difficult to read, reason about, extend. JITLink is designed to isolate
format and architecture specific code, while still sharing generic code.

(2) Support for native code models.

RuntimeDyld required the use of large code models (where calls to external
functions are made indirectly via registers) for many of platforms due to its
restrictive model for stub generation (one "stub" per symbol). JITLink allows
arbitrary mutation of the atom graph, allowing both GOT and PLT atoms to be
added naturally.

[X86] Disable argument copy elision for arguments passed via pointers

Summary:
If you pass two 1024 bit vectors in IR with AVX2 on Windows 64. Both vectors will be split 
in four 256 bit pieces. The four pieces of the first argument will be passed indirectly 
using 4 gprs. The second argument will get passed via pointers in memory.

The PartOffsets stored for the second argument are all in terms of its original 1024 bit 
size. So the PartOffsets for each piece are 32 bytes apart. So if we consider it for copy 
elision we'll only load an 8 byte pointer, but we'll move the address 32 bytes. The stack 
object size we create for the first part is probably wrong too.

This issue was encountered by ISPC. I'm working on getting a reduce test case, but wanted 
to go ahead and get feedback on the fix.

[CorrelatedValuePropagation] Mark subs that we know not to wrap with nuw/nsw.

Summary:
Teach CorrelatedValuePropagation to also handle sub instructions in addition to add. 
Relatively simple since makeGuaranteedNoWrapRegion already understood sub instructions. 
Only subtle change is which range is passed as "Other" to that function, since sub isn't 
commutative.

Note that CorrelatedValuePropagation::processAddSub is still hidden behind a default-off 
flag as IndVarSimplify hasn't yet been fixed to strip the added nsw/nuw flags and causes a 
miscompile. (PR31181)

[X86] Don't turn (and (shl X, C1), C2) into (shl (and X, (C1 >> C2), C2) if the original 
AND can represented by MOVZX.

The MOVZX doesn't require an immediate to be encoded at all. Though it does use
a 2 byte opcode so its the same size as a 1 byte immediate. But it has a
separate source and dest register so can help avoid copies.

[X86] Turn (and (anyextend (shl X, C1), C2)) into (shl (and (anyextend X), (C1 >> C2), C2) 
if the AND could match a movzx.

There's one slight regression in here because we don't check that the immediate
already allowed movzx before the shift. I'll fix that next.

[WebAssembly] Emit the DataCount section when bulk memory is enabled

Summary:
The DataCount section is necessary for the bulk memory operations
memory.init and data.drop to validate, but it is not recognized by
engines that do not support bulk memory, so emit the section only if
bulk-memory is enabled.

Modules: Adopt template parameters for variable templates to set their decl context

Exposed by a related bug about visibility of default arguments of nested
