Debug [Compiler]: Fix spurious "Que, numbers out of whack" diagnostic
The Supporter field "previous" is only valid while the supporter is
linked into the current_supporter chain. After that it should not be
accessed. verify_supporters accesses it anyway, so zero it out when
unlinking the supporter to prevent the debug code from acting on stale
information.

Testsuite [Compiler]: Fixed fall-out from the named/unnamed class change.
This fixes the testsuite failures due to the following two changes:
* Anonymous classes not being allowed at top level.
* Named classes no longer being expressions.

[compiler][amd64] Use new features from peep.c
Place the code for calling check_threads_etc before the function instead of
inside it, to have one branch less in tight loops.
This saves about 4% in the nested loops test, at the cost of 12 bytes extra
code-space for functions that do not actually contain loops (for functions
that contain loops 3 bytes is saved intead)
One alternative would have to place the code after the function, if it does
contain a loop, then update the relative jumps to point to the code.
That is left for later.

[compiler][amd64] Attempt at faster PC updates.
Always just assign PC to the current address instead of adding the
difference. This is somewhat faster.
We still do too many updates, though.
As an example it is commont to have 2-3 update_pc in a row.

[compiler][amd64] Inline version of FOREACH
This is the old foreach( array, loop_variable ). About 10 times faster if the
loop variable is a local variable in the function.

[compiler][amd64] Yet more inlined opcodes
Added inline versions of INDEX, INT_NDEX, NEG_INT_INDEX, LOCAL_INDEX.
They are only inlined when the index is an integer and the item to be
indexed is an array.
Adding support for string[int] might be useful.

[compiler][amd64] Real mov16 and mov8 added.
Using the movzx instruction, this is for unsigned numbers. Versions
using movsz is needed if signed numbers are to be used.
Inlined a few more opcodes. Fixed branch when (non) zero and branch
when local to correctly treat 0.0 as non-zero.
Fixed clearing of zero type in ADD_LOCAL_INT[_and_pop] and
ADD_[NEG_]INT.

[compiler][amd64] Cleaned up code somewhat and faster branches
Added FAST_BRANCH_WHEN{_,_NOT_}ZERO that knows that sp[-1] is an
integer. It can thus avoid doing any checking of types and the normal
pop_stack checks.
Also inlined the normal BRANCH_WHEN{_,_NON_}ZERO.
There is now a common function that is used to generate
modrm+sib+offset for the *mem* family of functions.
Also removed frame init/stack cleaning for Functions that just return
a constant.

[compiler] Significantly faster simple loops
New opcodes:
ASSIGN_LOCAL_NUMBER_AND_POP
ADD_LOCAL_NUMBER_AND_POP, ADD_LOCAL_LOCAL_AND_POP
and ASSIGN_GLOBAL_NUMBER_AND_POP
The rationale for the assign_local variants is that it is
significantly faster to do local=local and local+=[number||local] than
it is to do local&, number, f_add_to and similar.
The reason being that the locals act much like registers, they are
easy to assign values from the machinecode level.
Also added some perhaps dubious optimizations of the code that the
treeoptimizer produce for for-loops.
The result of the above is that the NestedLoops* tests are about eight
times faster. And runs entirely in native code, without any function
calls.

[compiler][amd64] Some more optimizations and changes
Added branch_check_threads_etc calls that went missing.
Also changed how branch_check_threads_etc is called, the code now
maintains a counter on the C-stack, if adding 1 to it (as a signed
byte) causes it to overflow the C-function is called, after adding 128
to the in-memory counter. This saves rather a lot of calls.
Inlined F_{DUMB_,}RETURN, F_BRANCH_WHEN_{EQ,NE} F_ADD_NEG_INT,
F_ADD_INT and F_ADD_INTS.
