f20968bc33 give branch folding a simple heuristic to decide which block to split so that
it inserts an uncond branch where it is less likely to cause a problem.  This
fixes some perf issues on ppc.

61ea2af8fe Turn a phi of many loads into a phi of the address and a single load of the
result.  This can significantly shrink code and exposes identities more
aggressively.

b459c08384 make tail merging more aggressive. If two blocks share a common tail, but the
tail is not an entire block for either of them, pick one, split it, then
merge the common part.

e6ba8a819c 1. Clean up code due to changes in SwitchTo*Section(2)
2. Added partial debug support for mingw\cygwin targets (the same as
   Linux\ELF). Please note, that currently mingw\cygwin uses 'stabs' format
   for storing debug info by default, thus many (runtime) libraries has
   this information included. These formats shouldn't be mixed in one binary
   ('stabs' & 'DWARF'), otherwise binutils tools will be confused.

a9f10b25cc Turn an assert into an error message. This is commonly triggered when
we don't support a specific constraint yet.  When this happens, print the
unsupported constraint.
