67cbd23ad5 Seperate asmstring parsing from emission. This allows the code to be simpler
and more understandable.  It also allows us to do simple things like fold
consequtive literal strings together.  For example, instead of emitting this
for the X86 backend:

  O  << "adc" << "l" << " ";

we now generate this:

  O << "adcl ";

*whoa* :)

This shrinks the X86 asmwriters from 62729->58267 and 65176->58644 bytes
for the intel/att asm writers respectively.

24bf1ca350 If the interpreter tries to execute an external function, kill it. Of course
since we are dirty, special case __main.  This should fix the infinite loop
horrible stuff that happens on linux-alpha when configuring llvm-gcc.  It
might also help cygwin, who knows??

bd8da4c80e Apparently destroyFile() now throws an exception. Since this class is
designed to be put on the stack, that's not cool.  Catch and ignore the
exception.

5a9660aa71 Add two optimizations. The first folds (X+Y)-X -> Y
The second folds operations into selects, e.g. (select C, (X+Y), (Y+Z))
-> (Y+(select C, X, Z)

This occurs a few times across spec, e.g.

         select    add/sub

fde1a5688b Implement Regression/CodeGen/X86/rotate.ll: emit rotate instructions (which
typically cost 1 cycle) instead of shld/shrd instruction (which are typically
6 or more cycles).  This also saves code space.

For example, instead of emitting:

rotr:
        mov %EAX, DWORD PTR [%ESP + 4]
        mov %CL, BYTE PTR [%ESP + 8]
        shrd %EAX, %EAX, %CL
        ret
rotli:
        mov %EAX, DWORD PTR [%ESP + 4]
        shrd %EAX, %EAX, 27
        ret

Emit:

rotr32:
        mov %CL, BYTE PTR [%ESP + 8]
        mov %EAX, DWORD PTR [%ESP + 4]
        ror %EAX, %CL
        ret
rotli32:
        mov %EAX, DWORD PTR [%ESP + 4]
        ror %EAX, 27
        ret

We also emit byte rotate instructions which do not have a sh[lr]d counterpart
at all.
