3a7489a4cc CodeGen still defaults to non-verbose asm, but llc now overrides it and default to verbose.

fca05e3a5c Add a -no-implicit-float flag. This acts like -soft-float, but may generate 
floating point instructions that are explicitly specified by the user.

880e63bf01 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.

5e78e558ff Add support to the JIT for true non-lazy operation. When a call to a function 
that has not been JIT'd yet, the callee is put on a list of pending functions
to JIT.  The call is directed through a stub, which is updated with the address
of the function after it has been JIT'd.  A new interface for allocating and
updating empty stubs is provided.

Add support for removing the ModuleProvider the JIT was created with, which
would otherwise invalidate the JIT's PassManager, which is initialized with the
ModuleProvider's Module.

Add support under a new ExecutionEngine flag for emitting the infomration 
necessary to update Function and GlobalVariable stubs after JITing them, by
recording the address of the stub and the name of the GlobalValue.  This allows
code to be copied from one address space to another, where libraries may live
at different virtual addresses, and have the stubs updated with their new
correct target addresses.

9dc1507838 Turns out AnalyzeBranch can modify the mbb being analyzed. This is a nasty 
suprise to some callers, e.g. register coalescer. For now, add an parameter
that tells AnalyzeBranch whether it's safe to modify the mbb. A better
solution is out there, but I don't have time to deal with it right now.

66f10b55ed New feature: add support for target intrinsics being defined in the 
target directories themselves.  This also means that VMCore no longer
needs to know about every target's list of intrinsics.  Future work
will include converting the PowerPC target to this interface as an
example implementation.

e442452ade Enable emitting of constant values in non-default address space as well. The APIs emitting constants now take an additional parameter signifying the address space in which to emit. The APIs like getData8BitsDirective() etc are made virtual enabling targets to be able to define appropirate directivers for various sizes and address spaces.

9d120d6d8f Make x86's BT instruction matching more thorough, and add some 
dagcombines that help it match in several more cases. Add
several more cases to test/CodeGen/X86/bt.ll. This doesn't
yet include matching for BT with an immediate operand, it
just covers more register+register cases.

bc43253a91 Make isOperationLegal do what its name suggests, and introduce a 
new isOperationLegalOrCustom, which does what isOperationLegal
previously did.

Update a bunch of callers to use isOperationLegalOrCustom
instead of isOperationLegal. In some case it wasn't obvious
which behavior is desired; when in doubt I changed then to
isOperationLegalOrCustom as that preserves their previous
behavior.

This is for the second half of PR3376.

c971801ae1 Eliminate a couple of fields from TargetRegisterClass: SubRegClasses and SuperRegClasses. These are not necessary. Also eliminate getSubRegisterRegClass and getSuperRegisterRegClass. These are slow and their results can change if register file names change. Just use TargetLowering::getRegClassFor() to get the right TargetRegisterClass instead.

190d6bc636 Fix PR3274: when promoting the condition of a BRCOND node, 
promote from i1 all the way up to the canonical SetCC type.
In order to discover an appropriate type to use, pass
MVT::Other to getSetCCResultType.  In order to be able to
do this, change getSetCCResultType to take a type as an
argument, not a value (this is also more logical).
