Remove 'asm' statements by compiling them into suitable standard goto program instructions.

Inline assembly statements in the source program (in either gcc- or msc-style) are represented by instructions of kind OTHER with a code member of type code_asmt in the goto program.

For example, the gcc inline assembly statement below

would be represented by a code_asmt statement with op0() being the string literal "mov %1, %0; add 1,ドル %0" (as a string_constantt expression) and op1(), op2(), and op3(), respectively, containing the output list, input list, and clobbered registers.

The remove_asm() function replaces the inline assembly statements in a given goto program with appropriate (sequences of) non-assembly goto program instructions.

It first parses the assembly instructions string (via assembler_parsert ) and inspects the input/output/clobber lists. Then, it generates a sequence of goto program instructions that either directly implement the assembly instructions, or call a suitable library function (see library/x86_assembler.c ).

At present only a small number of x86 and Power instructions are supported. Unrecognised assembly instructions are ignored (i.e., they are simply removed from the goto program).
