Rafael Espindola 7521964d28 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.

// can also be override to flush with the -cl-denorms-are-zero compiler flag.

// AMD OpenCL only sets flush none and reports CL_FP_DENORM for double

// CL_FP_DENORM for CL_DEVICE_SINGLE_FP_CONFIG. Mesa's OpenCL currently reports
// CL_FP_DENORM for both.

// regardless of the mode (exp_*_f32, rcp_*_f32, rsq_*_f32, rsq_*f32, sqrt_f32,
// and sin_f32, cos_f32 on most parts).
// We want to use these instructions, and using fp32 denormals also causes
// instructions to run at the double precision rate for the device so it's
