Georgii Rymar 4845531fa8 [lib/Object] - Refine interface of ELFFile<ELFT>. NFCI.
`ELFFile<ELFT>` has many methods that take pointers,
though they assume that arguments are never null and
hence could take references instead.

This patch performs such clean-up.

Jared Wyles ef454c5444 [jitlink] Adding support for PCRel32GOTLoad in ELF x86 for the jitlinker
Summary: This adds the basic support for GOT in elf x86.
Was able to just get away using the macho code by generalising the edges.
There will be a follow up patch to turn that into a generic utility for both of the x86 and Mach-O code.

This patch also lands support for relocations relative to symbol.

Lang Hames a6deaeec37 [JITLink] Improve llvm-jitlink regression testing support for ELF.
This patch adds a jitlink pass, 'registerELFGraphInfo', that records section
and symbol information about each LinkGraph in the llvm-jitlink session object.
This allows symbols and sections to be referred to by name in llvm-jitlink
regression tests. This will enable a testcase to be written for
https://reviews.llvm.org/D80613.

Simon Pilgrim c9797cf98b Fix msvc "switch statement contains 'default' but no 'case' labels" warning. NFC.
Stripped out the switch statement, but kept case labels as comments for future reference.

Lang Hames 2e40cf06df [JITLink] Initial implementation of ELF / x86-64 support for JITLink.
This initial implementation supports section and symbol parsing, but no
relocation support. It enables JITLink to link and execute ELF relocatable
objects that do not require relocations.

Patch by Jared Wyles. Thanks Jared!
