df597bf000 [NFC][ORC][AArch64] use isInt<N> to replace fitsRangeSignedInt on aarch64
Summary:
This is the first path to support more relocation types on aarch64.
 The patch just uses the isInt<N> to replace fitsRangeSignedInt.

Test Plan:

091e364866 [JITLink][ELF] Support duplicated section names from object file
ELF object files can contain duplicated sections (thus section symbols
as well), espeically when comdats/section groups are present. This patch
adds support for generating LinkGraph from object files that have
duplicated section names. This is the first step to properly model
comdats/section groups.

118e953b18 Re-apply "[JITLink] Update JITLink to use ExecutorAddr rather... " with fixes.
This re-applies 133f86e95492b2a00b944e070878424cfa73f87c, which was reverted in
c5965a411c635106a47738b8d2e24db822b7416f while I investigated bot failures.

The original failure contained an arithmetic conversion think-o (on line 419 of
EHFrameSupport.cpp) that could cause failures on 32-bit platforms. The issue
should be fixed in this patch.

133f86e954 [JITLink] Update JITLink to use ExecutorAddr rather than JITTargetAddress.
ExecutorAddr is the preferred representation for executor process addresses now.

9691851582 [JITLink] Factor out forEachRelocation() function from addRelocations() in ELF Aarch64 backend (NFC)
First step in reducing redundancy in `addRelocations()` implementations across ELF JITLink backends. The patch factors out common logic for ELF relocation traversal into the new helper function `forEachRelocation()` in the `ELFLinkGraphBuilder` base class. For now, this is applied to the Aarch64 implementation. Others may follow soon.

2ed91da0f1 [JITLink] Add initial Aarch64 support
Set up basic infrastructure for 64-bit ARM architecture support in JITLink. It allows for loading a minimal object file and resolving a single relocation. Advanced features like GOT and PLT handling or relaxations were intentionally left out for the moment.

This patch follows the idea to keep implementations for ARM (32-bit) and Aaarch64 (64-bit) separate, because:
* it might be easier to share code with the MachO "arm64" JITLink backend
* LLVM has individual targets for ARM and Aaarch64 as well
