S_scan_heredoc: fresh sv functions close to point of use
S_scan_heredoc does a SvGROW on a fresh PVIV. A sv_grow_fresh is
more efficient, plus it seems only really needed in the nearby "else"
branch. In the "if" branch, sv_setsv_fresh can be used directly.

sv.c - add SvPVCLEAR_FRESH macro for new PVs with buffer
SvPVCLEAR(tmpstr) is a macro that calls sv_setpv_bufsize(tmpstr,0,0).
If called on a newly minted PV/PVIV/PVNV/PVMG that has a fresh PV
buffer assigned, many of the checks in SvPVCLEAR are unnecessary:
* SvTHINKFIRST - won't be set
* upgrade to SVt_PV - won't be necessary
* SvGROW - we assert that this isn't necessary
It then does some useful, but small actions:
* sets SvCUR(sv, 0);
* sets the last byte in the PV buffer to \0
* sets SvPOK_only_UTF8
* does SvTAINT
Then does a final irrelevant check:
* is tmpstr a PVCV - no it is not
This commit introduces SvPVCLEAR_FRESH as a drop-in replacement
for compatible SVs, that only does the relevant small actions.

vnewSVpvf - inline & reduce call to sv_vsetpvfn
sv_vsetpvfn does just two things:
* SvPVCLEAR on the sv passed in
* calls sv_vcatpvfn_flags
Since the SV passed into sv_vsetpvfn by vnewSVpvf is a brand new SV,
it is more efficient to inline sv_vsetpvfn and change the SvPVCLEAR
to SvPVCLEAR_FRESH.
