Log Message:
-----------
Remove invalid DATA_ADDRESS_IS_SANE checks.
https://bugs.webkit.org/show_bug.cgi?id=304031
rdar://166329603
Reviewed by Dan Hecht.
Previous in 301407@main, I added DATA_ADDRESS_IS_SANE checks when we
HAVE(36BIT_ADDRESS).
Turns out that we may not be able to guarantee that addresses are 36-bits.
Hence, these
checks are invalid. This patch will remove the checks, while leaving the
HAVE(36BIT_ADDRESS) macro alone for now.
No new tests because this patch only removes invalid assertions.
