Fixed small bug.

Added gp_rel relocations to support addressing small section contents.
Added command line to specify small section threshold in bytes.

Added HasABICall and HasAbsoluteCall (equivalent to gcc -mabicall and 
-mno-shared). HasAbsoluteCall is not implemented but HasABICall is the 
default for o32 ABI. Now, both should help into a more accurate 
relocation types implementation. 
Added IsLinux is needed to choose between asm directives.
Instruction name strings cleanup.
AsmPrinter improved.

providing a misleading facility. It's used once in the MIPS backend
and hardcoded as "\t.globl\t" everywhere else.

Fixed some AsmPrinter issues
Added GLOBAL_OFFSET_TABLE Node handle.
