Similar to `FILECHECK_OPTS` for FileCheck, `LIT_OPTS` makes it easy to
adjust lit behavior when running the test suite via ninja. For
example:
```
$ LIT_OPTS='--time-tests -vv --filter=threadprivate' \
ninja check-clang-openmp

Previously, the llvm-readelf documentation was essentially just a list
of differences to llvm-readobj. Since llvm-readelf is the more likely
goto tool for many people migrating to the LLVM toolchain, it seems like
it would be helpful to document all the switches in the llvm-readelf
document too. This change expands the options listed accordingly.
Additionally, they are unlikely to care what the differences are to
llvm-readobj, since they won't be familiar with the latter as there is
no GNU equivalent, so this change moves the "differences" section to
llvm-readobj's documentation.

Sphinx allows for definitions of command-line options using
`.. option <name>` and references to those options via `:option:<name>`.
However, it looks like there is no scoping of these options by default,
meaning that links can end up pointing to incorrect documents. See for
example the llvm-mca document, which contains references to -o that,
prior to this patch, pointed to a different document. What's worse is
that these links appear to be non-deterministic in which one is picked
(on my machine, some references end up pointing to opt, whereas on the
live docs, they point to llvm-dwarfdump, for example).
The fix is to add the .. program <name> tag. This essentially namespaces
the options (definitions and references) to the named program, ensuring
that the links are kept correct.

There were a number of issues with the llvm-readobj documentation. The
following points were raised in https://bugs.llvm.org/show_bug.cgi?id=42255,
and have been fixed in this patch:
1. The description section claimed "The tool and its output is
primarily designed for use in FileCheck-based tests" which is not
really the case any more.
2. The documentation used single-dash long options for option names,
but references in the help text to other options exclusively used
double-dashes. Fixed by standardising on double-dashes for all
long-form options.
3. The majority of options available and in the help text were not
present in the documentation. This patch adds them.
4. Several aliases, both long and short, were missing, e.g. --relocs.
Additionally, this patch improves the documentation by:
1. Splitting the options into categories based on the file format they
are specific to.
2. Updating the Exit Status section to correctly mention that errors
lead to a non-zero exit code.
3. Adding a See Also section referencing other similar LLVM tools.
4. Improving/correcting some of the descriptions of options that did
not quite match up with what llvm-readobj does.

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.

Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch introduces the @LINE numeric
expressions.
This commit introduces a new syntax to express a relation a numeric
value in the input text must have with the line number of a given CHECK
pattern: [[#<@LINE numeric expression>]]. Further commits build on that
to express relations between several numeric values in the input text.
To help with naming, regular variables are renamed into pattern
variables and old @LINE expression syntax is referred to as legacy
numeric expression.
Compared to existing @LINE expressions, this new syntax allow arbitrary
spacing between the component of the expression. It offers otherwise the
same functionality but the commit serves to introduce some of the data
structure needed to support more general numeric expressions.
