    Also fix integer argument parsing rule for JMPI, IF and WHILE
    Fix shift/reduce conflicts in relativelocation

    brd: redirect channels to branches
    brc: let channels converging together
    
    also rewrite code converting label to offset

    Merge replicative code in gram.y

commit 22e4490848868259cdff141082c1824623360acb
Author: Homer Hsing <homer.xing at intel.com>
Date:   Fri Sep 21 10:06:20 2012 +0800

    Reduce replicative code in gram.y by reloc_target field in src_operand
    
    Bspec says JIP and UIP should be the source operands. It is better if
    src_operand has a field "reloc_target" according to bspec.
    The replicative code in JMPI and branchloop rules can be merged into one.

    Restrict type of relativelocation2 to int
    
    Original rule set it to EXP | NUMBER, then YYERROR if it is NUMBER.
    This patch set it directly to EXP, restricting its type to int.

commit 73857f8ac6cca19fe0e2580382f2949a27cfe89d

Date:   Fri Sep 21 09:37:06 2012 +0800

    Rewrite label matching code. Collect labels in a linked list.
    
    Label matching is faster because of searching only in a small list,
    rather than searching a label in all instructions.

Date:   Fri Sep 21 08:39:57 2012 +0800

    Add second_reloc_target in the data structure.
    
    Since Gen6+, some branching instructions have two relocation targets.

    Add test case for ".declare" overriding feature.
    
    Later same name .declare pragma will override previously defined
    one. This patch add a test case for that feature.

    Fix memory leaking in the parser
    
    STRING has been malloc'ed by strdup in src/lex.l but forgotten to
    be freed in src/gram.y.
