Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch adds support for selecting a
matching format to match a numeric value against (ie. decimal, hex lower
case letters or hex upper case letters).
This commit allows to select what format a numeric value should be
matched against. The following formats are supported: decimal value,
lower case hex value and upper case hex value. Matching formats impact
both the format of numeric value to be matched as well as the format of
accepted numbers in a definition with empty numeric expression
constraint.
Default for absence of format is decimal value unless the numeric
expression constraint is non null and use a variable in which case the
format is the one used to define that variable. Conclict of format in
case of several variable being used is diagnosed and forces the user to
select a matching format explicitely.
This commit also enables immediates in numeric expressions to be in any
radix known to StringRef's GetAsInteger method, except for legacy
numeric expressions (ie [[@LINE+<offset>]] which only support decimal
immediates.

Without this patch, `FILECHECK_OPTS` isn't propagated to FileCheck's
test suite so that `FILECHECK_OPTS` doesn't inadvertently affect test
results by affecting the output of FileCheck calls under test. As a
result, `FILECHECK_OPTS` is useless for debugging FileCheck's test
suite.
In `llvm/test/FileCheck/lit.local.cfg`, this patch provides a new
subsitution, `%ProtectFileCheckOutput`, to address this problem for
both `FILECHECK_OPTS` and the deprecated
`FILECHECK_DUMP_INPUT_ON_FAILURE`. The rest of the patch uses
`%ProtectFileCheckOutput` throughout the test suite
Fixes PR40284.

Summary:
Testing of caret location in diagnostic message is currently made with
CHECK directive with the following general format:
CHECK: {{^ \^$}}
James Henderson suggested the following would be more readable:
CHECK: {{^}} ^{{$}}
and when whole lines can be matched (as is the case for command-line
testing where error messages do not include path):
CHECK: ^
using the option --match-full-lines.
This commit implements these 2 changes on all existing caret position
tests. It also aligns the caret to the character it is trying to match
in the above line.

Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch lift the restriction for a
numeric expression to either be a variable definition or a numeric
expression to try to match.
This commit allows a numeric variable to be set to the result of the
evaluation of a numeric expression after it has been matched
successfully. When it happens, the variable is allowed to be used on
the same line since its value is known at match time.
It also makes use of this possibility to reuse the parsing code to
parse a command-line definition by crafting a mirror string of the
-D option with the equal sign replaced by a colon sign, e.g. for option
'-D#NUMVAL=10' it creates the string
'-D#NUMVAL=10 (parsed as [[#NUMVAL:10]])' where the numeric expression
is parsed to define NUMVAL. This result in a few tests needing updating
for the location diagnostics on top of the tests for the new feature.
It also enables empty numeric expression which match any number without
defining a variable. This is done here rather than in commit #5 of the
patch series because it requires to dissociate automatic regex insertion
in RegExStr from variable definition which would make commit #5 even
bigger than it already is.

Summary:
Both callers of parseNumericVariableDefinition() perform the same extra

Summary:
This patch is part of a patch series to add support for FileCheck

numeric variable in a CHECK directive.
This commit introduces support for defining numeric variable from a
litteral value in the input text. Numeric expressions can then use the
variable provided it is on a later line.

Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch introduces regular numeric
variables which can be set on the command-line.
This commit introduces regular numeric variable that can be set on the
command-line with the -D option to a numeric value. They can then be
used in CHECK patterns in numeric expression with the same shape as
@LINE numeric expression, ie. VAR, VAR+offset or VAR-offset where offset
is an integer literal.
The commit also enable strict whitespace in the verbose.txt testcase to
check that the position or the location diagnostics. It fixes one of the
existing CHECK in the process which was not accurately testing a
location diagnostic (ie. the diagnostic was correct, not the CHECK).
