Mono treats UIntPtr fields in mscorlib as potential
reference fields since they may store non-object
GC memory there. Liveness assumes all GC memory
as determined via the GC descriptor points to
objects. Take slow scan path of field types
rather than GC descriptor in cases where the
gc descriptor may have bits set for non-object memory.

Move thread exit check within loop.

Take fast path only for delegate types not Delegate/MulticastDelegate…

Avoids race condition between checking for exit,
thread exiting, and thread suspension logic.

Scripting memory capture fixes for old mono

* fixed incorrect offseting during the iteration of mempool blocks
* enforced stopping the world before we walk any data inside the current domain
* enforced starting the world only after we've collected all snapshot data

Add loop to avoid assert from failing call to GetThreadContext (case …

Calls GetThreadContext (and perhaps SuspendThread) can fail.
This seems to be due to race condition with thread either
being in protected code or invalid state (exiting). Use
loop of SuspendThread/GetThreadContext/ResumeThread(on failure)
to retry suspension logic.

Move GetThreadContext to suspend step and cache in per thread
CONTEXT. This ensures we can get a CONTEXT for each suspended thread.

Remove the 32-bit slice from the Mono runtime

Apple is not allowing Mac App Store submissions with 32-bit slices in
universal binaries any longer. We don't use the 32-bit slice in Mono, so
remove it.

Don't call sa_sigaction when it is NULL

It is possible for the sa_sigaction callback to be NULL. This happens
for abort signal. Calling a NULL method will cause the signal handler to
hang, which will cause Unity to hang, instead of crashing. This can be
unhelpful when tests are running, for example.

Fix metadata parsing

GC enable/disable APIs for unity-trunk

[runtime] Fix the size calculation for CustomAttributeType coded indexes, they can only point to the MethodDef/MemberRef tables even through 3 bits are used to encode them, only 2 values are used. Fixes #58210. (#5256)

The memberref table is not a valid option for computing the
MemberRefParent tag size.

Use Boehm GC_ functions in mono_unity_gc_enable/disable instead of mono_gc_ functions.
