general case and handle all 7.x versions the same.

This change only affects whether packages are built or not.

Fix debugger launch race hitting breakpoints in startup code. (dotnet/coreclr#8951)

The attached flag was been set asynchronously relative to the DebugActiveProcess
returning.  This could cause a race where the initial module load notification being
missed/not sent to the debugger.

This fix sets the attached flag before any notifications sent during launch if the runtime was
launched/attached using the startup handshake after dbgshim tells the runtime to "continue"
when the runtime startup API callback returns.

Also fixes another race condition in dbgshim where EnumerateCLRs returns a NULL continue event
handle because the coreclr module was loaded but the g_hContinueStartupEvent wasn't initialized
on the runtime side yet. Changed the static initialization of g_hContinueStartupEvent to
INVALID_HANDLE_VALUE and the InternalEnumerateCLRs sleep/retry loop to retry when any of the
handles are INVALID_HANDLE_VALUE. This fixes the race only when you have the latest dbgshim
and coreclr binaries and the old/new mixes still function but don't fix the race.

Implement NYI(Cast) of codegen for Ryujit ARM32

Implement genIntToIntCast(), genFloatToFloatCast(),
genIntToFloatCast() and genFloatToIntCast() in codegenarm.cpp.
This commit bases upon ARM64 code.
(Code for int64/uint64 is marked as NYI_ARM)

Enable promotion of SIMD fields of structs

Commit migrated from https://github.com/dotnet/coreclr/commit/26a6391c6e05c41bf48beaf529684ad44f3b3fa6

Enable promotion of SIMD fields of structs

Only look for SIMD fields if a SIMD type has been found.
Also, since more cases of local struct values are no longer marked GTF_GLOB_REF, adjust the heuristics for allocating a temporary for a struct arrRef.

Fix dotnet/coreclr#7508

Fix arm32 build break

Commit migrated from https://github.com/dotnet/coreclr/commit/3243366c41c0f80deddc72101c50932954e7a001

Fix arm32 build break

fgClearFinallyTargetBit requires computePreds to have happened in order
to sucessfully leave the bit unset for cases where there are multiple
CALLFINALLY / BBJ_ALWAYS pairs that point to the same finally target on
ARM.

The change adds an assertion to fgClearFinallyTargetBit in addition
to disabling the optimization on ARM.

Add mkdir for CoreFx directory

In PR 8997 I accidentally removed the mkdir that creates the corefx
directory for us to copy the test zip into.  I did this when I was
adding Https to the URLs that we use to download the information from
Jenkins.  This adds back that bit.
