Start refactoring of asmprinters: provide a TAI hook, which will select a 'section kind' for a global.

Make intel asmprinter child of generic asmprinter, not x86 shared asm printer. This leads to some code duplication, which will be resolved later.

happy bootstrap land.

information of the original load or store, which is checked to be
at least as good, and possibly better.

of a std::string.  This avoids copying the string to the heap in common
cases.  Patch by Pratik Solanki!

This speeds up a particular testcase from 0.0302s to 0.0222s in LiveVariables.

This speeds up LiveVariables from 0.6279s to 0.6165s on kimwitu++.

tolerate a non-nul-terminated string, and handling a direct global 
reference.

global is constant already.  No functionality change.

Don't perform expensive queries checking for super and sub registers when we know that there aren't any.
This speed up LiveVariables on instcombine at -O0 -g from 0.3855s to 0.3503s.  Look for more improvements in this area soon!

- Make sure that we're not recalculating the size of a vector
  that never changes.

llvm-svn: 52803

some uses of std::vector, where it's return std::vector by value. Yuck!

This patch add supports for single architecture mach-o files (the current implementation only support Universal Binary), and solve the signature conflict between java class and Universal Binary magics.

Note that this function will always returned dynamic library for Universal Binaries (like the current implementation) because the binary type is not include in the file header."
