Bill Wendling 7a87a78c6c DWARF requires frame moves be specified at specific times. If you have a 
prologue like this:

__Z3fooi:
Leh_func_begin1:
LBB1_0: ## entry
        pushl   %ebp
Llabel1:
        movl    %esp, %ebp
Llabel2:
        pushl   %esi
Llabel3:
        subl    $20, %esp
        call    "L1$pb"
"L1$pb":
        popl    %esi

The "pushl %ebp" needs a table entry specifying the offset. The "movl %esp,
%ebp" makes %ebp the new stack frame register, so that needs to be specified in
DWARF. And "pushl %esi" saves the callee-saved %esi register, which also needs
to be specified in DWARF.

Before, all of this logic was in one method. This didn't work too well, because
as you can see there are multiple FDE line entries that need to be created.

This fix creates the "MachineMove" objects directly when they're needed; instead
of waiting until the end, and losing information.

Chris Lattner a8b6961b6c fix some type confusion in ReadVBR64: "Piece" should be only 32 bits, 
not 64, because we read at most 32 bits at a time.  OTOH, "Result" must
be 64-bits and insertion into it must be 64-bit clean.  Thanks to Ivan
Sorokin for bringing this up.

Chris Lattner 72a743fc47 "BinaryObject.h was implicitly converting between uint{16,32,64}_t to 
uint8_t (via 'foo & 255'), i replaced this with an explicit (uint8_t)
cast which is equivalent, faster and more correct (silences
type-related warnings). Also, following coding standards I replaced
post-increment with pre-increment."

Chris Lattner 3612256e2e Eliminate the static constructors and locks from DynamicLibrary.cpp. 
This fixes PR4512 and eliminating static ctors is always good.  Losing
thread safety is unfortunate, but the code is just incredibly poorly
designed.

If someone is interested, the "right" solution is to split
DynamicLibrary.cpp into two separate pieces: a stateless piece in
libsystem, and a simple support file in libsupport that has the
"state" (e.g.  AddSymbol) in managed static objects.

Doing this would both fix memory leaks we already have, as well as make
the code thread safe again.  it would also make sense to move all the
unix specific code in System/DynamicLibrary.cpp into 
System/Unix/DynamicLibrary.inc.

Torok Edwin 6c2d233e7a Introduce new error handling API. 
This will replace exit()/abort() style error handling with an API
that allows clients to register custom error handling hooks.
The default is to call exit(1) when no error handler is provided.

Sanjiv Gupta 031bbef528 if the terminator is a branch depending upon the side effects of a 
previous cmp; a copy can not be inserted here if the copy insn also has
 side effects. We don't have access to the attributes of copy insn here;
 so just play safe by finding a safe locations for branch terminators.
