## Check:
## 1) Simple constant as address.
## 2) That something that contains ":" character, like ternary

## 3) That complex expressions work.
## 4) That section alignment still applied to explicitly specified address.

[ELF] Set MAXPAGESIZE to 2MiB on x86-64 to match bfd and gold. The FreeBSD kernel relies on this behavior to not overwrite the boot loader. llvm-svn: 278889
