Recommitted 266457 with fix: * Do script driven layout only if SECTIONS section exist. Initial commit message: [ELF] - Implemented basic location counter support. This patch implements location counter support. It also separates assign addresses for sections to assignAddressesScript() if it scipt exists. Main testcase is test/ELF/linkerscript-locationcounter.s, It contains some work with location counter. It is basic now. Implemented location counter assignment and '+' operations. Patch by myself with LOTS of comments and design suggestions from Rui Ueyama. Differential revision: http://reviews.llvm.org/D18499 llvm-svn: 266526

[LLD][ELF] - Update tests after r352366. r352366 "[llvm-objdump] - Print LMAs when dumping section headers." changed the format of llvm-objdump output. We have to update the LLD tests. llvm-svn: 352372

[ELF] Assign RF_EXEC rank even if --no-rosegment or SECTIONS command is used Summary: Currently when --no-rosegment is specified or a linker script with SECTIONS command is used, .rodata (A) .text (AX) are assigned the same rank and .rodata may be placed after .text . This increases the gap between .text and .bss and can cause pc-relative relocation overflow (e.g. gcc crtbegin.o crtbegin.S have R_X86_64_PC32 relocation from .text to .bss). This patch makes SingleRoRx affect only segment layout, not section layout. As a consequence, .rodata will be placed before .text regardless of SingleRoRx.
