6731be3175 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.

57328aa902 ARM asm parsing should handle pre-indexed writeback w/o immediate. 
For example, 'ldrb r9, [sp]!' is odd, but valid.

82df2a3e37 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.

cfc77bc719 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.

4149334f09 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.
