Summary:
A commit may, for some reason, have `llvm-svn:` in it multiple times. It may even take up the whole line and look identical to what gets added automatically when svn commits land in github.
To workaround this, make changes to both lookups:
1) When doing the git -> svn lookup, make sure to go through the whole message, and:
a) Only look for llvm-svn starting at the beginning of the line (excluding the whitespace that `git log` adds).
b) Take the last one (at the end of the commit message), if there are multiple matches.
2) When doing the svn -> git lookup, look through a sizeable but still reasonably small number of git commits (10k, about 4-5 months right now), and:
a) Only consider commits with the '^llvm-svn: NNNNNN' we expect, and
b) Only consider those that also follow the same git -> svn matching above. (Error if it's not exactly one commit).

Summary:
Terminology introduced by [[#]] blocks is confusing and does not
integrate well with existing terminology.
First, variables referred by [[]] blocks are called "pattern variables"
while the text a CHECK directive needs to match is called a "CHECK
pattern". This is inconsistent with variables in [[#]] blocks since
[[#]] blocks are also found in CHECK pattern yet those variables are
called "numeric variable".
Second, the replacing of both [[]] and [[#]] blocks by the value of the
variable or expression they contain is represented by a
FileCheckPatternSubstitution class. The naming refers to being a
substitution in a CHECK pattern but could be wrongly understood as being
a substitution of a pattern variable.
Third and lastly, comments use "numeric expression" to refer both to the
[[#]] blocks as well as to the numeric expressions these blocks contain
which get evaluated at match time.
This patch solves these confusions by
- calling variables in [[]] and [[#]] blocks as string and numeric
variables respectively;
- referring to [[]] and [[#]] as substitution *blocks*, with the former
being a string substitution block and the latter a numeric
substitution block;
- calling [[]] and [[#]] blocks to be replaced by the value of a
variable or expression they contain a substitution (as opposed to
definition when these blocks are used to defined a variable), with the
former being a string substitution and the latter a numeric
substitution;
- renaming the FileCheckPatternSubstitution as a FileCheckSubstitution
class with FileCheckStringSubstitution and
FileCheckNumericSubstitution subclasses;
- restricting the use of "numeric expression" to refer to the expression
that is evaluated in a numeric substitution.
While numeric substitution blocks only support numeric substitutions of
numeric expressions at the moment there are plans to augment numeric
substitution blocks to support numeric definitions as well as both a
numeric definition and numeric substitution in the same numeric
substitution block.

**Many** AMDGPU tests specify `-march`, not `-mtriple`, which results in `update_llc_test_checks.py`
defaulting to x86 asm function detection heuristics, which don't work here.
I propose to fix this by adding an infrastructure to map from `-march` to `-mtriple`,
in the UpdateTestChecks tooling.

zlib/nozlib, asan/not_asan, msan/not_msan, ubsan/not_ubsan.
We still have two other ways to express the absence of a feature.
First, we have the '!' operator to invert the sense of a keyword. For
example, given a feature that depends on zlib being unavailable, its
test can say:
REQUIRES: !zlib
Second, if a test doesn't play well with some features, such as
sanitizers, that test can say:
UNSUPPORTED: asan, msan
The different ways of writing these exclusions both have the same
technical effect, but have different implications to the reader.

When builing the hermetic static library, the compiler switch
-fvisibility-global-new-delete-hidden is necessary to get the new and
delete operator definitions made correctly. However, when those
definitions are not included in the library, then this switch does harm.
With lld (though not all linkers) setting STV_HIDDEN on SHN_UNDEF
symbols makes it an error to leave them undefined or defined via dynamic
linking that should generate PLTs for -shared linking (lld makes this a
hard error even without -z defs). Though leaving the symbols undefined
would usually work in practice if the linker were to allow it (and the
user didn't pass -z defs), this actually indicates a real problem that
could bite some target configurations more subtly at runtime. For
example, x86-32 ELF -fpic code generation uses hidden visibility on
declarations in the caller's scope as a signal that the call will never
be resolved to a PLT entry and so doesn't have to meet the special ABI
requirements for PLT calls (setting %ebx). Since these functions might
actually be resolved to PLT entries at link time (we don't know what the
user is linking in when the hermetic library doesn't provide all the
symbols itself), it's not safe for the compiler to treat their
declarations at call sites as having hidden visibility.

Not all versions of git support git rev-parse --git-common-dir. Rather than erorr or print any kind of
useful error, they just print back '--git-common-dir' instead of a directory. The git-llvm script
ends up taking this '--git-common-dir' as a diretory name to use.
Not sure exactly what happens after that, but the end result is that the 'git llvm push' ends up
looking like it pushed your commits, but really did nothing.
This patch makes the script detect the bogus directory name for --git-common-dir and falls back to using --git-dir instead.

Various tests in the `lit` testing suite expect specific return codes
and forms of diagnostic message from utility programs. As per
POSIX.1-2017 XCU Section 1.4, Utility Description Defaults, "[the]
format of diagnostic messages for most utilities is unspecified".
The STDERR subsections of the `cat` and `wc` utilities merely indicate
that "[the] standard error shall be used only for diagnostic messages".
The corresponding EXIT STATUS subsections merely indicate, with regard
to errors, an exit value of >0.
The affected tests are updated to accept the applicable diagnostic
message as produced by the utilities on AIX. The exit value is
normalized using `not` as necessary.

Multiple targets in the same output directory can use the same

When that's the case, the object files produced for each target
are going to conflict. Using the label_name avoids this conflict
since labels are guaranteed to be unique within a single BUILD.gn
