NAS-138706 / 26.04 / Fix typo in NFS bindip validator. (#17724)
The validator had a typo. The intent is to convert `None` to the string
`'None'`
Fix associated CI test.
Add deactivation symbol operand to ConstantPtrAuth.
Deactivation symbol operands are supported in the code generator by
building on the previously added support for IRELATIVE relocations.

Add IR and codegen support for deactivation symbols.
Deactivation symbols are a mechanism for allowing object files to disable
specific instructions in other object files at link time. The initial use
case is for pointer field protection.

strfmon: Fix negative sign handling for C locale
If the locale's positive_sign and negative_sign values would both be
returned by localeconv() as empty strings, strfmon() shall behave as if
the negative_sign value was the string "-".
This occurs with the C locale. The implementation previously assigned
"0" to sign_posn (parentheses around the entire string); now it assigns
it to "1" (sign before the string) when it is undefined (CHAR_MAX).
Austin Group Defect 1199[1] is applied, changing the requirements for
the '+' and '(' flags.

strfmon: Add tests for Austin Group Defect 1199
Add tests for The Open Group Base Specifications Issue 8[1], Austin
Group Defect 1199[2].
Items marked with XXX represent an invalid output. These items will be
fixed in subsequent commits.
Notice that an existing test is now considered invalid.
Our locale definitions do not include int_p_sep_by_space nor
int_n_sep_by_space[3]. Those will be addressed in a subsequent commit.
However, the CLDR project defines them as "0", which causes the output
to appear as "USD123.45". If our locale definitions were to set the
international {n,p}_sep_by_space to "1", the output would display as the
expected "USD 123.45".

CodeGen: Optionally emit PAuth relocations as IRELATIVE relocations.
This supports the following use cases:
- ConstantPtrAuth expressions that are unrepresentable using standard PAuth
relocations such as expressions involving an integer operand or
deactivation symbols.
- libc implementations that do not support PAuth relocations.

[CIR][NFC] Fix build problem inside an assert (#169715)
A recent change introduced a failure in debug builds due to an incorrect
level of indirection inside an assert. This fixes that.
