5684598f3f Make BB and CPI labels use the function number, not the function name as a 
uniquing id.  This makes things happy when the function name is quoted,
preventing labels like LBB"foo"_2.

not spending tons of time microoptimizing it.  This is useful for an -O0

ae232e7a10 Add the necessary support to the ISel to allow targets to codegen the new

fixed-size allocas with alignment larger than the stack.  Support for
arbitrarily aligned dynamic allocas coming soon.

out failed (e.g. methcall) - now the code compiles, though it's not quite

f2db9b88da DAG->DAG instruction selection for ia64! "hello world" works, not much else. 
use -enable-ia64-dag-isel to turn this on

TODO: delete lowering stuff from the pattern isel
    : get operations on predicate bits working
    : get other bits of pseudocode going
    : use sampo's mulh/mull-using divide-by-constant magic
    : *so* many patterns ("extr", "tbit" and "dep" will be fun :)
    : add FP
    : add a JIT!
    : get it working 100%

in short: this'll be happier in a couple of weeks, but it's here now so
the tester can make me feel guilty sooner.

OTHER: there are a couple of fixes to the pattern isel, in particular
making the linker happy with big blobs of fun like pypy.

da32c9eed6 Make a new reg class for 64 bit regs that aliases the 32 bit regs. This 
will have to tide us over until we get real subreg support, but it prevents
the PrologEpilogInserter from spilling 8 byte GPRs on a G4 processor.

Add some initial support for TRUNCATE and ANY_EXTEND, but they don't
currently work due to issues with ScheduleDAG.  Something wll have to be
figured out.

43f07a4bbc another solution to the fsel issue. Instead of having 4 variants, just force 
the comparison to be 64-bits.  This is fine because extensions from float
to double are free.

ca0a4778a8 Minor tweak to the branch selector. When emitting a two-way branch, and if 
we're in a single-mbb loop, make sure to emit the backwards branch as the
conditional branch instead of the uncond branch.  For example, emit this:

LBBl29_z__44:
        stw r9, 0(r15)
        stw r9, 4(r15)
        stw r9, 8(r15)
        stw r9, 12(r15)
        addi r15, r15, 16
        addi r8, r8, 1
        cmpw cr0, r8, r28
        ble cr0, LBBl29_z__44
        b LBBl29_z__48                   *** NOT PART OF LOOP

Instead of:

LBBl29_z__44:
        stw r9, 0(r15)
        stw r9, 4(r15)
        stw r9, 8(r15)
        stw r9, 12(r15)
        addi r15, r15, 16
        addi r8, r8, 1
        cmpw cr0, r8, r28
        bgt cr0, LBBl29_z__48            *** PART OF LOOP!
        b LBBl29_z__44

The former sequence has one fewer dispatch group for the loop body.

d145a61f8f Darwin, like many BSD systems, has a setjmp/longjmp which saves the signal mask 
on setjmp calls and restores it on longjmp calls (both of which require syscalls).

This makes the calls REALLY slow.  Use _setjmp/_longjmp instead.  This speeds up
hexxagon from 120.31s to 15.68s: from 5.53x slower than GCC to 28% faster than GCC.

4345a4a452 Fix some issues exposed by more testing. XORIS had the wrong operands 
specified.  The various *imm operands defined by PPC are really all i32,
even though the actual immediate is restricted to a smaller value in it.

7b738342f0 Change the arg lowering code to use copyfromreg from vregs associated 
with incoming arguments instead of the pregs themselves.  This fixes
the scheduler from causing problems by moving a copyfromreg for an argument
to after a select_cc node (now it can, and bad things won't happen).
