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.

Fix consumeReg order for ArrOffs on arm64

Fix Linux perf run script

We rely on the build of CoreFX that we grab from the Corefx runs on the
main Jenkins instance.  With the recent changes the name of one of the
folders as been changed from "Native" to "native".  The checking that we
were doing was not case insensitive and as a result we started failing.
I have made that check now look for both the upper case and lower case
version of the word.

Unsuppress heap use marking for legacy codegen

This change extends the same fix from dotnet/coreclr#8757 to legacy-codegen.cpp; a prior
heap def in a block is not sufficient to avoid marking a subsequent heap
use in that block upwards-exposed (without proof that the def writes the
same memory read by the use).

Fix inter-block heap-live-in calculation

Similar to the intra-block case fixed in dotnet/coreclr#8757, without proving that a
heap def completely covers a subsequent heap use, we must propagate heap
liveness up past the heap def.  Fix failure to so propagate liveness in
`LiveVarAnalysis::PerBlockAnalysis`.

Refactor GT_IND value-numbering

Method `fgValueNumberTree` had two pieces of code each attempting to
assume responsibility for `GT_IND` and some block ops.  The one later in
the function wasn't reachable because those ops would always take the
first path.  This change moves the special logic for `GTF_IND_ARR_LEN`,
which was only present in the unreachable code, up to the reachable code,
and removes the unreachable code.

Fix DateTimeFormatInfo serialization on Unix

The Unix copy of the src is missing some [NonSerialized] attribution on a few of its fields, one of which is for a field of type TokenHashValue, which isn't [Serializable].  This is causing DateTimeFormatInfo to itself fail to serialize.
