Sumanth Gundapaneni d5aa0f3464 [Hexagon] Emit lookup tables in text section based on a flag
The flag "-hexagon-emit-lut-text" (defaulted to false) is added to decide
on where to keep the switch generated lookup table.

Sumanth Gundapaneni 8c5d59557d [Hexagon] Emit jump tables in text section based on a flag
This patch adds a new LLVM flag -hexagon-emit-jt-text which is defaulted to 
"false". The value "true" emits the switch generated jump tables in text section.

Sumanth Gundapaneni cf73758dc8 [Hexagon] Guard the generation of lookup table
The llvm flag "-hexagon-emit-lookup-tables" guards the generation
of lookup table from a switch statement.

Peter Collingbourne 6733564e5a Target: Change various section classifiers in TargetLoweringObjectFile to take a GlobalObject.
These functions are about classifying a global which will actually be
emitted, so it does not make sense for them to take a GlobalValue which may
for example be an alias.

Change the Mach-O object writer and the Hexagon, Lanai and MIPS backends to
look through aliases before using TargetLoweringObjectFile interfaces. These
are functional changes but all appear to be bug fixes.

Rafael Espindola 0709a7bd1a Move alignment from MCSectionData to MCSection.
This starts merging MCSection and MCSectionData.

There are a few issues with the current split between MCSection and
MCSectionData.

* It optimizes the the not as important case. We want the production
of .o files to be really fast, but the split puts the information used
for .o emission in a separate data structure.

* The ELF/COFF/MachO hierarchy is not represented in MCSectionData,
leading to some ad-hoc ways to represent the various flags.

* It makes it harder to remember where each item is.

The attached patch starts merging the two by moving the alignment from
MCSectionData to MCSection.

Most of the patch is actually just dropping 'const', since
MCSectionData is mutable, but MCSection was not.

Benjamin Kramer a7c40ef022 Canonicalize header guards into a common format.
Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)

Changes made by clang-tidy with minor tweaks.

Rafael Espindola fa0f72837f Pass the Mangler by reference.
It is never null and it is not used in casts, so there is no reason to use a
pointer. This matches how we pass TM.

Eric Christopher 2037caf8b9 Revert r199871 and replace it with a simple check in the debug info
code to see if we're emitting a function into a non-default
text section. This is still a less-than-ideal solution, but more
contained than r199871 to determine whether or not we're emitting
code into an array of comdat sections.

Eric Christopher 15abef6df9 Add a variable to track whether or not we've used a unique section,
e.g. linkonce, to TargetMachine and set it when we've done so
for ELF targets currently. This involved making TargetMachine
non-const in a TLOF use and propagating that change around - I'm
open to other ideas.

This will be used in a future commit to handle emitting debug
information with ranges.
