use the more precise 'op1' instead of 'var1' since the latter can be misunderstood to not encompass constants

ModuleBuilder now performs llvmgen in HandleTranslationUnit.

This patch follows from the discussion on the following thread on cfe-commits:

llvm-svn: 54486

Fixed bug in adjustMipsStackFrame, which was breaking
while trying to access a dead stack object index. Also added
one more alignment before fixing the callee saved registers
stack offset adjustment.

FPROUND_F80_F32, FPROUND_PPCF128_F32, 
FPROUND_F80_F64, FPROUND_PPCF128_F64

Support for soften float fp_round operands is added, Mips 
needs this to round f64->f32.

Also added support to soften float FABS result, Mips doesn't 
support double fabs results while in 'single float only' mode.

Do a dominator walk when scheduling copies, rather than a DFS on the CFG.  Also, fix a few problems when creating
live intervals for temporaries created by phi elimination.

Fix by Jordan Breeding: when scanning for prior runs, scan-build should ignore files that are not directories.

Fix --html-diags in driver by delaying the construction of an HTMLDiagnosticClient until after we have created the Preprocessor object.

with support for objc but not with support for objc++.

LowerSubregs, and fix an x86-64 isel bug that this exposed.

SUBREG_TO_REG for x86-64 implicit zero extension is only safe for
isel to generate when the source is known to always have zeros in
the high 32 bits. The EXTRACT_SUBREG instruction does not clear
the high 32 bits.
