Fix some problems in SpeculativelyExecuteBB. Basically,
...
because of dead code, a phi could use the speculated instruction
that was not in "BB2". Make this check explicit and tighten up
some other corners. This fixes PR3292. No testcase becauase this
depends entirely on visitation order of blocks and requires a
sequence of 8 passes to repro.

putc, puts, perror, vscanf and vsscanf from getting annotations.
Add annotations for eight printf functions, memalign, pread and pwrite.
On Linux, llvm-gcc sometimes renames strdup, getc, putc, strtok_r, scanf and
sscanf. Match the alternate function names.
Fix a crash annotating opendir.
Don't mark fsetpos's second parameter as nocapture. It's supposed to be
captured.
Do mark fopen's path and mode strings as nocapture. Mark ferror as readonly,
but not fileno which may set errno.

Implement a special algorithm for converting uint_to_fp for i32 values on
...
X86. This code:
void f() {
uint32_t x;
float y = (float)x;
}
used to be:
movl %eax, -8(%ebp)
movl [2^52 double], -4(%ebp)
movsd -8(%ebp), %xmm0
subsd [2^52 double], %xmm0
cvtsd2ss %xmm0, %xmm0
Is now:
movsd [2^52 double], %xmm0
movsd %xmm0, %xmm1
movd %ecx, %xmm2
orps %xmm2, %xmm1
subsd %xmm0, %xmm1
cvtsd2ss %xmm1, %xmm0
This is faster on X86. Note that there's an extra load of %xmm0 into %xmm1. That
will be fixed in a later coalescer fix.

Instead of adding dependence edges between terminator instructions
...
and every other instruction in their blocks to keep the terminator
instructions at the end, teach the post-RA scheduler how to operate
on ranges of instructions, and exclude terminators from the range
of instructions that get scheduled.
Also, exclude mid-block labels, such as EH_LABEL instructions, and
schedule code before them separately from code after them. This
fixes problems with the post-RA scheduler moving code past
EH_LABELs.

CreateVirtualRegisters does trivial copy coalescing. If a node def is used by a single CopyToReg, it reuses the virtual register assigned to the CopyToReg.
