Anton Korobeynikov e765f2b5e3 Describe what's going on with mingw alloca and why do we need separate instruction.

Anton Korobeynikov ce7bf1c55f Initial bits of ARMv4-only support. 
Patch by John Tytgat!

Anton Korobeynikov 043f3c2a0e Lower dynamic stack allocation on mingw32 to separate instruction. 
We cannot use a normal call here since it has extra unmodelled side
effects (it changes stack pointer). This should fix PR5292.

Anton Korobeynikov 9aff323a07 Do not use '&' prefix for globals when register base field is non-zero, otherwise msp430-as will silently miscompile the code (TI's assembler report an error though). 
This fixes PR6349

Anton Korobeynikov 293d592bf9 It turned out that we failed to emit proper symbol stubs on non-x86/darwin for ages (we emitted a reference to a stub, but no stub was emitted). The code inside x86-32/macho target objfile lowering should actually be the generic one - move it there. 
This (I really, really hope) should fix EH issues on ppc/darwin
and arm/darwin.

Anton Korobeynikov ac8a3d0b5b It turns out that we emitted completely wrong common EH frame since the early beginning! The "z" CIE augmentation mark indicates that there is an extra word containing the size of augmentation section. However, even for frames w/o any augmentation data we emitted size uleb! (this is the case of "unwinding through C code"). Thus frame moves information was emitterd completely wrong.

Anton Korobeynikov 90cfc130d6 Fix a gross typo: ARMv6+ may or may not support unaligned memory operations. 
Even if they are suported by the core, they can be disabled
(this is just a configuration bit inside some register).

Allow unaligned memops on darwin and conservatively disallow them otherwise.

Anton Korobeynikov 7b1eb8a409 Remove uber-gross hack. The define _snprintf to snprintf is invalid due to two reasons: 1. Accroding to C++ standard snprintf should be available in std namespace (and __gnu_cxx in case of GCC to). Such ifdef will change all snprintf's to _snprintf's, but won't bring snprintf to all necessary namespaces. Thus e.g. any locale-using code on mingw will yield an error (include this file + string to see the result) 2. MSVCRT's _snprintf does not comply with C99 standard. Standard one is snprintf.

Anton Korobeynikov 5cdc3a949a Materialize global addresses via movt/movw pair, this is always better 
than doing the same via constpool:
1. Load from constpool costs 3 cycles on A9, movt/movw pair - just 2.
2. Load from constpool might stall up to 300 cycles due to cache miss.
3. Movt/movw does not use load/store unit.
4. Less constpool entries => better compiler performance.

This is only enabled on ELF systems, since darwin does not have needed
relocations (yet).
