Sean Callanan eab6cc98d7 The expression parser will now check the validity 
of the "self"/"this" pointer for the current stack
frame before wrapping expressions in C++ or
Objective-C methods.  This works around bad debug
info where the compiler emits a "this" or "self"
but doesn't give any way to find its location.

Evan Cheng 5213139f48 Let targets provide hooks that compute known zero and ones for any_extend 
and extload's. If they are implemented as zero-extend, or implicitly
zero-extend, then this can enable more demanded bits optimizations. e.g.

define void @foo(i16* %ptr, i32 %a) nounwind {
entry:
  %tmp1 = icmp ult i32 %a, 100
  br i1 %tmp1, label %bb1, label %bb2
bb1:
  %tmp2 = load i16* %ptr, align 2
  br label %bb2
bb2:
  %tmp3 = phi i16 [ 0, %entry ], [ %tmp2, %bb1 ]
  %cmp = icmp ult i16 %tmp3, 24
  br i1 %cmp, label %bb3, label %exit
bb3:
  call void @bar() nounwind
  br label %exit
exit:
  ret void
}

This compiles to the followings before:
        push    {lr}
        mov     r2, #0
        cmp     r1, #99
        bhi     LBB0_2
@ BB#1:                                 @ %bb1
        ldrh    r2, [r0]
LBB0_2:                                 @ %bb2
        uxth    r0, r2
        cmp     r0, #23
        bhi     LBB0_4
@ BB#3:                                 @ %bb3
        bl      _bar
LBB0_4:                                 @ %exit
        pop     {lr}
        bx      lr

The uxth is not needed since ldrh implicitly zero-extend the high bits. With
this change it's eliminated.

Sean Callanan faa0bb3fa1 Rewrote the bitfield logic. Major changes include: 
- Removed the BitfieldMap class because it is unnecessary.
  We now just track the most recently added field.

- Moved the code that calculates bitfield widths so it
  can also be used to determine whether it's necessary
  to insert anonymous fields.

- Simplified the anonymous field calculation code into
  three cases (two of which are resolved identically).

- Beefed up the bitfield testcase.

Richard Smith 69c87b0914 PR10867. lit would interpret 
RUN: a
  RUN: b || true

as "a && (b || true)" in Tcl mode, and as "(a && b) || true" in sh mode.
Everyone seems to (quite reasonably) write tests assuming the Tcl behavior,
so use that in sh mode too.

Richard Smith c524ec4411 Fix an egregiously broken test. This pattern doesn't work: 
RUN: a
RUN: b || true

lit expands it to a && b || true, and the || true applies to both commands (thus ignoring failures in 'a')! This is PR10867 again.

Eli Bendersky 02631c4e31 Change std::vector to SmallVector<4> and remove some unused methods. 
This is more consistent with other vectors in this code. In addition, I ran some
tests compiling a large program and >96% of fragments have 4 or less fixups, so
SmallVector<4> is a good optimization.

David Sehr 05176cad21 Correct ARM NOP encoding 
The encoding of NOP in ARMAsmBackend.cpp is missing a trailing zero, which
causes the emission of a coprocessor instruction rather than "mov r0, r0"
as indicated in the comment.  The test also checks for the wrong encoding.

Michael J. Spencer 0c6ec48d0b Add dump of Win64 EH unwind data. 
The new command line option -unwind-info dumps the Win64 EH unwind

Michael J. Spencer fa8e8c5193 Updates to Win64EH.h structures. 
Change member types of RuntimeFunction and UnwindInfo from uint64_t to
uint32_t:
These members represent addresses. According to MSDN, they are image
relative, that is, they are 32-bit offsets from the starting address
of the image that contains the function table entry.
See MSDN for more information:
RUNTIME_FUNCTION: http://msdn.microsoft.com/en-us/library/ft9x1kdx.aspx
UNWIND_INFO: http://msdn.microsoft.com/en-us/library/ddssxxy8.aspx

Make Win64.h platform-neutral:
The standard types unit8_t, uint16_t and uint32_t are replaced with
their counterparts from Endian.h. Accessor functions are introduced to
replace bit fields.

Patch by João Matos and Kai Nacke.
