For simplicity in splitting out UBSan options into separate rules,
remove CONFIG_UBSAN_SANITIZE_ALL, effectively defaulting to "y", which
is how it is generally used anyway. (There are no ":= y" cases beyond
where a specific file is enabled when a top-level ":= n" is in effect.)

Drop "the" from the title of the documentation article for UBSAN, as it is
redundant.
Also add SPDX-License-Identifier for ubsan.rst.

ubsan: remove UBSAN_MISC in favor of individual options2020-12-16T06:46:19+00:00Kees Cookkeescook@chromium.org2020-12-16T04:46:39+00:00urn:sha1:c637693b20da8706b7f48d96882c9c80ae935151
Make each UBSAN option individually selectable and remove UBSAN_MISC which
no longer has any purpose. Add help text for each Kconfig, and include a
reference to the Clang sanitizer documentation. Disable unsigned overflow
by default (not available with GCC and makes x86 unbootable with Clang).
Disable unreachable when objtool is in use (redundant and confuses things:
instrumentation appears at unreachable locations).
