Bill Wendling e7b02b8170 Replace more uses of 'unwind' in the tests with calls to landingpad and 
resume. Note that some of these tests were basically dead.

Bill Wendling c945f54ea5 This testcase is dead. It doesn't inline even if I add the 'alwaysinline' 
attribute to the @foo function.

Akira Hatanaka 79738336a8 Make changes to avoid creating nested CALLSEQ_START/END constructs, which aren't 
yet legal according to comments in LegalizeDAG.cpp:227. 

Memcpy nodes created for copying byval arguments are inserted before
CALLSEQ_START.

The two failing tests reported in PR10876 pass after applying this patch.

Jim Grosbach 40700e0992 ARM asm parsing should handle pre-indexed writeback w/o immediate. 
For example, 'ldrb r9, [sp]!' is odd, but valid.

Benjamin Kramer 43a772eda1 Add a MachO-specific "mode" to llvm-objdump, that, if enabled, gathers additional information that are only available on MachO. 
- It can take FunctionStarts from a binary to find entry points more accurately.
- Symbol offsets in executables are correct now.

Nadav Rotem 7ae11279e9 When promoting integer vectors we often create ext-loads. This patch adds a 
dag-combine optimization to implement the ext-load efficiently (using shuffles).

For example the type <4 x i8> is stored in memory as i32, but it needs to
find its way into a <4 x i32> register. Previously we scalarized the memory
access, now we use shuffles.

Duncan Sands f2b8c854dd Synthesize x86 max/min instructions also for vectors (i.e. produce 
maxps and maxpd).  This broke the sse41-blend.ll testcase by causing
maxpd to be produced rather than a cmp+blend pair, which is the reason
I tweaked it.  Gives a small speedup on doduc with dragonegg when the
GCC vectorizer is used.
