968dc7a207 Reapply 68073, with fixes. EH Landing-pad basic blocks are not 
entered via fall-through. Don't miss fallthroughs from blocks
terminated by conditional branches. Also, move
isOnlyReachableByFallthrough out of line.

46801029ea Do not pass '-relocation-model=pic' to llc. 
Does not work well on 32 bit targets. Bug reported by Albert Graef.

This patch also adds new "-Wllc,option" syntax to pass options to llc.

be46c79501 Add llvm::sys::getHostTriple and remove 
llvm::sys::getOS{Name,Version}.

Right now the implementation just derives from LLVM_HOSTTRIPLE (which
is wrong, but it doesn't look like we have a define for the target
triple). Ideally this routine would actually be able to compute the
triple for targets we care about.

4d95232469 X86 address mode isel tweak. If the base of the address is also used by a CopyToReg (i.e. it's likely live-out), do not fold the sub-expressions into the addressing mode to avoid computing the address twice. The CopyToReg use will be isel'ed to a LEA, re-use it for address instead. 
This is not yet enabled.

80c93e7442 Except in asm-verbose mode, avoid printing labels for blocks that are 
only reachable via fall-through edges. This dramatically reduces the
number of labels printed, and thus also the number of labels the
assembler must parse and remember.

e6f350d755 Turn a 2-address instruction into a 3-address one when it's profitable even if the two-address operand is killed. 
e.g.
%reg1024<def> = MOV r1
%reg1025<def> = ADD %reg1024, %reg1026
r0            = MOV %reg1025

If it's not possible / profitable to commute ADD, then turning ADD into a LEA saves a copy.
