Rafael Espindola 6d6c6043ea X86-64 TLS support for local exec and initial exec.

Rafael Espindola bb834f0929 Don't fold a load if the other operand is a TLS address. 
With this we generate

movl    %gs:0, %eax
leal    i@NTPOFF(%eax), %eax

instead of

movl    $i@NTPOFF, %eax
addl    %gs:0, %eax

Rafael Espindola 3b2df10c9e Re-apply 68552. 
Tested by bootstrapping llvm-gcc and using that to build llvm.

Bill Wendling 4aa25b79f9 Temporarily revert r68552. This was causing a failure in the self-hosting LLVM 
builds.

Rafael Espindola 1edda06792 Reduce code duplication on the TLS implementation. 
This introduces a small regression on the generated code
quality in the case we are just computing addresses, not
loading values.

Will work on it and on X86-64 support.

Rafael Espindola 000421eade Refactor TLS code and add some tests. The tests and expected results are: 
pic |  declaration | linkage  | visibility |

!pic |  declaration | external | default    | tls1.ll     tls2.ll     | local exec
 pic |  declaration | external | default    | tls1-pic.ll tls2-pic.ll | general dynamic
!pic | !declaration | external | default    | tls3.ll     tls4.ll     | initial exec
 pic | !declaration | external | default    | tls3-pic.ll tls4-pic.ll | general dynamic

!pic |  declaration | external | hidden     | tls7.ll     tls8.ll     | local exec
 pic |  declaration | external | hidden     | X                       | local dynamic
!pic | !declaration | external | hidden     | tls9.ll     tls10.ll    | local exec
 pic | !declaration | external | hidden     | X                       | local dynamic

!pic |  declaration | internal | default    | tls5.ll     tls6.ll     | local exec
 pic |  declaration | internal | default    | X                       | local dynamic

The ones marked with an X have not been implemented since local dynamic is not implemented.

Dan Gohman 54ec4bfa5f Change the x86 assembly output to use tab characters to separate the 
mnemonics from their operands instead of single spaces. This makes the
assembly output a little more consistent with various other compilers
(f.e. GCC), and slightly easier to read. Also, update the regression
tests accordingly.
