[AArch64] Support optional constant offset for constraint "S" (#80255)
Modify the initial implementation (https://reviews.llvm.org/D46745) to
support a constant offset so that the following code will compile:
```
int a[2][2];
void foo() { asm("// %0" :: "S"(&a[1][1])); }
```
We use the generic code path for "s". In GCC's aarch64 port, "S" is
supported for PIC while "s" isn't, making "s" less useful. We implement
"S" but not "s".
Similar to #80201 for RISC-V.

[SimplifyCFG] HoistThenElseCodeToIf(): don't hoist if either block has it's address taken
This problem is exposed by D104598, after it tail-merges `ret` in
`@test_inline_constraint_S_label`, the verifier would start complaining
`invalid operand for inline asm constraint 'S'`.
Essentially, taking address of a block is mismodelled in IR.
It should probably be an explicit instruction, a first one in block,
that isn't identical to any other instruction of the same type,
so that it can't be hoisted.

[AArch64] Support "S" inline assembler constraint
This patch re-introduces the "S" inline assembler constraint. This matches
an absolute symbolic address or a label reference. The primary use case is
asm("adrp %0, %1\n\t"
"add %0, %0, :lo12:%1" : "=r"(addr) : "S"(&var));
I say re-introduces as it seems like "S" was implemented in the original
AArch64 backend, but it looks like it wasn't carried forward to the merged
backend. The original implementation had A and L modifiers that could be
used to print ":lo12:" to the string. It looks like gcc doesn't use these
and :lo12: is expected to be written in the inline assembly string so I've
not implemented A and L. Clang already supports the S modifier.
Fixes PR37180
