Haowei Wu a1d0589266 [llvm-elfabi] Add flag to preserve timestamp when output is the same 
This change adds '--write-if-changed' flag to llvm-elfabi tool. When
enabled, llvm-elfabi will not overwrite the existing file if the
content of the file will not be changed, which preserves the
timestamp.

Georgii Rymar ffbce65f95 [lib/Object, tools] - Make ELFObjectFile::getELFFile return reference. 
We always have an object, so we don't have to return a pointer.

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.
