- reduce default buffer size to 64, which will still be large enough to
  hold any property names found in the wild.
- get rid of the /*static*/ comments.

 - Split createAtom() in lib/ReaderWriter/ELF/File.h into small methods.
 - Added comments to code in other methods.

No functionality changes.

Previously LEA64_32r went through virtually the entire backend thinking it was
using 32-bit registers until its blissful illusions were cruelly snatched away
by MCInstLower and 64-bit equivalents were substituted at the last minute.

This patch makes it behave normally, and take 64-bit registers as sources all
the way through. Previous uses (for 32-bit arithmetic) are accommodated via
SUBREG_TO_REG instructions which make the types and classes agree properly.

The Logs directory isn't used for testing, so it's filtered out ahead of
time. However, there's then no reason to include it in version control at
all. Don't error if it's not present.

This warning triggers on the logical not of a non-boolean expression on the
left hand side of comparison.  Often, the user meant to negate the comparison,
not just the left hand side of the comparison.  Two notes are also emitted,
the first with a fix-it to add parentheses around the comparison, and the other
to put parenthesis around the not expression to silence the warning.

bool not_equal(int x, int y) {
  return !x == y;  // warn here
}

  return !(x == y);  // first fix-it, to negate comparison.

  return (!x) == y;  // second fix-it, to silence warning.

[PowerPC] Support extended sc mnemonic

A plain "sc" without argument is supposed to be treated like "sc 0"
by the assembler.  This patch adds a corresponding alias.

Problem reported by Joerg Sonnenberger.

[PowerPC] Support branch mnemonics with implied CR0

The extended branch mnemonics are supposed to use an implied CR0
if there is no explicit condition register specified.  This patch
adds extra variants of the mnemonics to this effect.

Problem reported by Joerg Sonnenberger.

[PowerPC] Use multiclass to generate extended branch mnemonics

This patch removes some redundancy by generating the extended branch
mnemonics via a multiclass.

We were looking at Magic[5] without checking Length. Since this path would not
return unless Length >= 18 anyway, just move the >= 18 check up.
