05334af883 (re)introduce new simpler apis for creation sectionkinds.

81229d1bed Remove "JumpTableDataSection" from TAI, instead, have AsmPrinter 
compute it based on what it knows.  As part of this, rename getSectionForMergeableConstant
to getSectionForConstant because it works for non-mergable constants also.

The only functionality change from this is that Xcore will start dropping
its jump tables into readonly section instead of data section in -static mode.
This should be fine as the linker resolves the relocations.  If this is a
problem, let me know and we'll come up with another solution.

8120a93944 give alpha its readonly section. This optimizes alpha, and prevents a 
testsuite regression with a coming patch.

e1cc2c27b3 fix a problem Eli noticed where we would compile the attached ptrtoint 
to:

.quad X

even on a 32-bit system, where X is not 64-bits.  There isn't much that
we can do here, so we just print:

.quad	((X) & 4294967295)

instead.

79e9585304 Change SectionKind to be a property that is true of a *section*, it 
should have no state that is specific to particular globals in the
section.  In this case, it means the removal of the "isWeak" and
"ExplicitSection" bits.  MCSection uses the new form of SectionKind.

To handle isWeak, I introduced a new SectionInfo class, which is
SectionKind + isWeak, and it is used by the part of the code generator
that does classification of a specific global.

The ExplicitSection disappears.  It is moved onto MCSection as a new
"IsDirective" bit.  Since the Name of a section is either a section
or directive, it makes sense to keep this bit in MCSection.  Ultimately
the creator of MCSection should canonicalize (e.g.) .text to whatever
the actual section is.

cd4d9ff7fa Hack to make this test work on platforms which aren't Macs. Fixing this 
myself because I'm getting tired of seeing the red buildbots, which have 
been red since 5:30PM PDT last night.

Proposed supplement to developer policy: committers should make sure to 
be around to watch for buildbot failures after committing.

5ef6928dff Fix Thumb2 function call isel. Thumb1 and Thumb2 should share the same 
instructions for calls since BL and BLX are always 32-bit long and BX is always
