ARM64: Enable Daily Job for GcStress0x3

ARM64: Test Update for GcStress0x3

Commit migrated from https://github.com/dotnet/coreclr/commit/b567823b332c347ebfc7bf5726df16dc6c38690a

Avoid box allocation in Encoding.EncodingName (dotnet/coreclr#6142)

`Encoding.EncodingName` concatenates a `string` with an `int` via
`string.Concat(object, object)`, which results in the `int` being
boxed.

This change avoids the box by calling `int.ToString()`,
allowing `string.Concat(string, string)` to be used.

Fix LLDB search order

By default 'find_library' without 'NO_DEFAULT_PATH' keyword searches
first in default locations specified by '${CMAKE_SYSTEM_PREFIX_PATH}'
and only then in locations specified via 'PATHS' keyword
('${WITH_LLDB_LIBS}' in our case). As result it always picks-up default
LLDB ignoring the one explicitly specified via '${WITH_LLDB_LIBS}'.
This change modifies search order giving priority to '${WITH_LLDB_LIBS}'
and '${WITH_LLDB_INCLUDES}' over default locations.

Named mutex: Use flock instead of pthread process-shared mutex in some more cases

Workaround for dotnet/coreclr#5456:
- Sometimes, a timed wait operation is not getting released, causing a hang
- Due to the hang, it is not possible to detect this issue with code
- Temporarily disabled the use of pthread process-shared mutexes on ARM/ARM64. File locks will be used instead.

Workaround for dotnet/coreclr#5872:
- On Alpine Linux, a pthread process-shared robust mutex is detecting the case where a process abandons the mutex when it exits while holding the lock, but is putting the mutex into an unrecoverable state (ENOTRECOVERABLE) instead of assigning lock ownership to the next thread that is released from a wait for a lock and notifying of abandonment (EOWNERDEAD).
- Added a test case to detect this issue, to have it use file locks instead

RyuJIT/x86: add support for EH

This change implements the necessary x86 support in RyuJIT for exception handling.
It removes the EH-related NYI. The number of NYI fallbacks in an x86 test run drops
by about 13000. There are 10 new asserts which are now suppressed: 6 appear to be
new and 4 are new instances of existing known asserts.

The various changes are:
1. Implement code generation for BBJ_CALLFINALLY/BBJ_ALWAYS blocks for invoking a finally.
This requires appropriately modifying the ShadowSP slot structure before the call.
2. Implement BBJ_EHFINALLYRET/BBJ_EHFILTERRET control transfer. The related GT_RETFILT
code was already implemented.
3. Implement GT_END_LFIN for handling return-from-finally cleanup, namely, clearing the
appropriate slot in the ShadowSP structure.

GC ETW fixes. The code for getting data for ETW and perf counter was written by different
folks and was very intertwined. For full CLR we always have both defined but for coreclr
perf counters are not enabled so some things for ETW were just 0. Need to make sure when one
is not defined the rest are still getting the data they need.

Inliner: make ModelPolicy available in release builds

Make the ModelPolicy available in release builds of the jit. Enable this
policy by setting:

   COMPLUS_JitInlinePolicyModel=1

This works for either jitting or prejitting.

Update the ModelPolicy so callee never inline decisions are always
propagated back to the runtime.
