2d4a054440 ir: fix generation of multi-op vinstrs 
Do not assume that the destination is a temporary location,
as our peephole optimizer will break this. For example, the
following IR code (generated via from `x ^= gety()`):

    (0) binst6 <- BITXOR   x,      call5
    (0) x <- STORE_F       binst6

after peephole optimization becomes:

    (7) x <- BITXOR        x,      call5

Therefore we cannot assume that the output of the virtual
xor instruction can be utilized as a temporary value.

BITXOR becomes `(x | y) - (x & y)`, which would wrongly be
generated as:
    x = x | y;
    temp0 = x & y;
    x = x - temp0;

While this particular case can be fixed by using temp0 first
and then x, the cross-product case would not be so simple.

031f827da5 introduce another vinstr temp 
Some vinstrs are currently broken when using peephole
optimization as they appear as writing to a temporary ssa
output before being stored into their real destination,
causing the store to be optimized out, but the generated
code relies on having the destination as another temporary
value available.

Let's just add a 2nd temp to be used in those cases.

Fix printing of floating poing values in -dumpfin. 
%g is not lossless for single precision floats - %.9g is (other than distinguishing NaNs, who cares).

97a74eb677 catch broken vector member access 
These kinds of expressions currently cannot be handled
without pionter support in the qcvm without scanning the
ast from within ast_member::codegen for an assignments as
seen in the added test case.

This change makes code like that return a pointer type which
will cause an error that we did not get a vector or field
back. With pointer support this pointer could actually be
used instead.

So at least it shouldn't silently produce broken code
anymore.

047ecd426f move more parser code to c++, fix crashes with gcc 
we initialized the parser with malloc -> memset to zero ->
placement new. With gcc the latter caused the memset to be
optimized out, causing uninitialized value accesses.
