8279204: [BACKOUT] JDK-8278413: C2 crash when allocating array of size too large

[shipilev]

Summary: This reverts commit deaf75a.

Roland is on vacation now, so we would not get the fix any time soon. Meanwhile, there are lots of test failures and GHA uncleanliness due to this patch.

Additional testing:

• Test failures from recorded bugs are gone
• Linux x86_64 fastdebug tier1
• Linux x86_64 fastdebug tier2
• Linux x86_64 fastdebug tier3
• GHA are clean

That seems reasonable. Looks good!

Thanks! Should I wait for 24 hours for this patch, or we consider clean backouts trivial?
